Ingredients

  • Quinoa
  • 1 cup quinoa ≈ 170 g
  • 2 cups vegetable broth or water
  • Peppers
  • 4 large red bell peppers
  • 1 tbsp olive oil
    Swaps for olive oil

    Instead of olive oil

    • Avocado oil or another neutral oil: The same amount. No olive flavor; avocado oil handles higher heat.
    • Butter: The same amount. Richer and nutty when browned.
    • A neutral oil + more seasoning: The same amount. Dressings lose the fruity, peppery note; a little extra lemon, garlic or mustard makes up for it.

    More for olive oil

  • 1 pinch kosher salt
    Swaps for kosher salt

    Instead of salt

    • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
    • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

    More for salt

  • Filling
  • 1 can chickpeas, 15 oz, drained and rinsed
  • 1 cup cherry tomatoes, quartered
  • ½ cup kalamata olives, chopped
  • ¼ small red onion, finely chopped
    Swaps for red onion

    Instead of onion

    • Another onion: The same amount. Yellow is the all-rounder; white is sharper and crisper; red is milder raw and adds color; sweet onions are mildest.
    • Shallots: The same amount, chopped. Milder and sweeter, with a hint of garlic.
    • Leeks: About 1½ times as much, white and light green parts. Milder and softer when cooked.

    All 4 swaps for onion

  • 2 cups baby spinach, chopped ≈ 60 g
  • 2 cloves garlic, minced
    Swaps for garlic

    Instead of garlic

    • Garlic powder: ⅛ tsp for each clove. Mellower and sweeter, with no bite.
    • Jarred minced garlic: ½ tsp for each clove. Milder and slightly sour from the preserving liquid.

    More for garlic

  • 1 tsp dried oregano
    Swaps for dried oregano

    Instead of oregano

    • Fresh oregano: 1 tbsp chopped fresh for each 1 tsp dried (three times as much). Brighter and more peppery; use a little less than you think.
    • Dried marjoram, Italian seasoning or dried basil: The same amount. Marjoram is milder, basil sweeter; Italian seasoning already has oregano in it.

    More for oregano

  • 2 tbsp olive oil
    Swaps for olive oil

    Instead of olive oil

    • Avocado oil or another neutral oil: The same amount. No olive flavor; avocado oil handles higher heat.
    • Butter: The same amount. Richer and nutty when browned.
    • A neutral oil + more seasoning: The same amount. Dressings lose the fruity, peppery note; a little extra lemon, garlic or mustard makes up for it.

    More for olive oil

  • 1 tbsp lemon juice
    Swaps for lemon juice

    Instead of lemon juice

    • Lime juice: The same amount. A different, more floral aroma; works almost everywhere.
    • Bottled lemon juice: The same amount. More sour and flatter; fine in cooking and baking, less bright in dressings and drinks.
    • White wine vinegar or white vinegar: Half as much. Sharper, with no citrus aroma.

    More for lemon juice

  • 1 tsp lemon zest
    Swaps for lemon zest

    Instead of citrus zest

    • Another citrus zest: The same amount. A different citrus aroma; any of them brightens a dish.
    • Dried citrus peel: 1 tsp dried for each 1 tbsp fresh zest. Milder and a little bitter.
    • Lemon or orange extract: About ¼ tsp extract for each 1 tsp zest, to taste. Strong citrus flavor, no texture.

    More for citrus zest

  • ½ tsp kosher salt
    Swaps for kosher salt

    Instead of salt

    • Table salt or fine sea salt: About half as much as Diamond Crystal kosher, about ¾ as much as Morton kosher. The same saltiness when measured this way.
    • Salt by weight: 1 tsp is about 6 grams of table salt, 5 grams of Morton kosher, 3 grams of Diamond Crystal kosher. The most reliable way to swap, especially in baking and brines.

    More for salt

  • ¼ tsp black pepper
  • 4 oz feta, crumbled (about 1 cup), divided
  • ¼ cup fresh parsley, chopped ≈ 15 g
    Swaps for fresh parsley

    Instead of parsley

    • Dried parsley: 1 tsp dried for each 1 tbsp chopped fresh (a third as much). Very mild; it adds color more than flavor.
    • Cilantro: The same amount. Stronger and citrusy; suits Mexican and Asian dishes.
    • Celery leaves or chervil: The same amount. Celery leaves are peppery and grassy; chervil is mild with a hint of anise.

Steps

  1. Heat the oven to 400°F (200°C).
    400°F
  2. Rinse the quinoa well in a fine-mesh strainer. Rinsing removes a bitter coating.
  3. Combine the quinoa and broth in a saucepan and bring to a
    boil (how to boil) Boil Heat liquid until big bubbles rise and break all over the surface. 1. Use a pot big enough that the water fills it no more than three quarters.2. Cover it to boil faster, over high heat.3. Salt pasta or vegetable water once it boils.4. Add the food, stir, and bring it back to a boil before you start timing. Done when: A rolling boil keeps bubbling hard even when you stir. Safety: Turn pot handles toward the back of the stove, and drain pasta into a colander in the sink, pouring away from you. Steam burns fast: lift lids and foil away from your face, tipping the far edge up first.How to boil water for pasta and vegetables: mistakes to avoid
    .
  4. Cover, turn the heat to low and
    simmer (how to simmer) Simmer Cook liquid just below a boil, with small bubbles breaking the surface now and then. 1. Bring the liquid up over medium-high heat.2. As soon as bubbles rise steadily, turn the heat down.3. Adjust until only a few small bubbles break the surface every second or two.4. Stir now and then and check that it hasn't crept back to a boil. Done when: You see lazy, small bubbles, not a rolling boil. A "bare" simmer has just a bubble here and there. Safety: Steam burns fast: lift lids and foil away from your face, tipping the far edge up first.How to simmer: mistakes to avoid
    until the liquid is absorbed.
    ⏱ Simmer quinoa: 15 min
  5. Take the pan off the heat and let it steam, still covered.
    ⏱ Steam: 5 min
  6. Cut the peppers in half lengthwise through the stem and remove the seeds and ribs.
  7. Set the halves cut side up in a 9x13 baking dish, brush with 1 tablespoon oil and sprinkle with a pinch of salt.
  8. Roast (how to roast) Roast Cook food uncovered in a hot oven so the outside browns while the inside cooks through. 1. Heat the oven fully before the food goes in, usually 400 to 450°F for vegetables.2. Toss vegetables with oil and salt; dry and season meat.3. Spread everything out on a sheet pan or in a roasting pan with room around each piece.4. Roast, turning vegetables once halfway, until browned at the edges.5. For meat, check the center with a thermometer. Done when: Vegetables are browned at the edges and tender in the middle; meat reaches its safe temperature. Safety: Use dry oven mitts (wet ones pass heat straight through) and tilt hot pans away from you to avoid the fat and steam.How to roast meat and vegetables: mistakes to avoid
