Cut bell peppers in half, remove seeds, and microwave them for about 2-3 minutes in a microwave safe bowl or dish with about ½” water in the bowl. This will help soften the peppers.
Meanwhile, prepare quinoa according to package directions.
In a large bowl, combine cooked quinoa, zucchini, beans, cilantro, onion, lime juice, garlic, cumin, smoked paprika, and salt & pepper together.
Place peppers in a large baking dish, cut side up, and fill each pepper evenly with the quinoa mixture.
Pour a can of enchilada sauce over all the peppers and then top evenly with the shredded cheese. Cover with aluminum foil, but make sure the foil is not touching the cheese.
