1: Preheat oven to 400°F.
2: In a 9"x13" baking dish, toss the bell pepper and the onion with the olive oil and season with salt and pepper. Spread out evenly in the baking dish, then roast in the oven for 30 minutes.
3: While veggies are baking, cook your quinoa according to the directions on packaging, using the veggie broth instead of water.
4: Once the peppers and onions are roasted, remove from oven and stir in the baby spinach, garlic, Italian seasonings, and white wine. Add the cooked quinoa, season well with salt and pepper and a dash of red pepper flakes, and stir until well combined.
5: Top with crumbled feta and bake for another 20 minutes. Broil for 3-5 minutes at the end until feta is slightly browned.
