Instructions

  1. Step 1: Preheat oven to 375°F. In a medium saucepan, bring 2 cups water to a boil. Add 1 cup rinsed quinoa, cover, reduce heat to low and simmer for 15 minutes until water is absorbed and quinoa is fluffy.
  2. Step 2: While quinoa cooks, heat 3 tbsp olive oil in a skillet over medium heat. Add 1 small diced yellow onion, 3 minced garlic cloves, 1 small diced zucchini, and 1 small diced carrot. Sauté for 6-7 minutes until vegetables are soft and fragrant.
  3. Step 3: In a large bowl, combine the cooked quinoa, sautéed vegetables, 1/4 cup chopped fresh parsley, 1 tsp dried oregano, 1/2 cup crumbled feta cheese, 1 tsp salt, 1/2 tsp black pepper, and 1 tbsp fresh lemon juice. Mix thoroughly.
  4. Step 4: Stuff the 4 prepared red bell peppers evenly with the quinoa-vegetable mixture. Place peppers upright in a baking dish and cover loosely with foil.
  5. Step 5: Bake for 35-40 minutes until peppers are tender but not mushy and the filling is heated through.
