Add the olive oil to a skillet over medium heat. Once hot, add the onion, garlic, and taco seasoning. Cook for 3 to 4 minutes until softened.
In a large bowl, mix together the onion mixture, quinoa, black beans, corn, salsa, green chiles, and non-dairy cheese.
Divide the quinoa-vegetable filling between the bell peppers and arrange them in a baking dish. Cover the dish with aluminum foil and bake for 20 minutes.
After 20 minutes, remove the foil and bake for another 20 minutes.
Top with avocado, salsa, lemon, and cilantro before serving. Enjoy!
Notes
For Italian-inspired vegetarian stuffed peppers, swap salsa with diced tomatoes, use zucchini instead of corn, and replace taco seasoning with Italian seasoning. And for a different take on stuffed peppers, use hotter ones like poblano pepper halves instead of bell peppers!
Cook the rice first to avoid crunchy grains in your veggie stuffed peppers!
For softer stuffed veggie peppers, roast the peppers! Place them cut side down on a baking sheet with parchment paper, drizzle with oil and season with salt, and roast for 10 to 15 minutes in the oven preheated to convection roast at 475ºF.
