Begin by washing the quinoa thoroughly under cold water. This helps remove any bitterness.
In a pot, bring 2 cups of water to a boil, add the quinoa, and let it simmer for about 15 minutes. Once cooked, fluff it up and set aside.
Preheat your oven to 375°F (190°C).
Prepare your veggies: chop zucchini, red onion, and halve the cherry tomatoes. Remember, these are the heart and soul of your Quinoa and Roasted Veggie Stuffed Peppers.
In a pan, heat the olive oil over medium heat. Once hot, add in the chopped red onion, minced garlic, and sauté until translucent.
Add zucchini and cherry tomatoes to the pan. Season with salt and pepper.
After 5 minutes, add the spinach and cook until it wilts.
Combine the veggie mixture with the cooked quinoa. Mix well.
Cut the tops off the bell peppers and deseed them.
Stuff each bell pepper with the quinoa and veggie mixture.
Place the stuffed peppers in a baking dish.
Pop the dish into the preheated oven and bake for about 25-30 minutes, or until the peppers are tender.
Garnish with freshly chopped basil, if desired.
