In a large bowl, combine the quinoa, diced tomatoes, corn, spinach, onion, garlic, feta, cilantro and spices until thoroughly mixed.
After the bell peppers have been wash, stems cut off and seeded take a spoon and fill each bell pepper cavity. Once bell pepper is filled place in your baking dish, and bake until the peppers are tender and the quinoa filling is hot.
I would add the mozzarella cheese the last 20 minutes of cooking so that it does not get too brown.
Takes about 35-40 minutes to cook.
