Creating delicious Homemade Breaded Veggie Burgers is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
2. Prepare Quinoa: If not already cooked, prepare your quinoa according to package instructions and set aside.
3. Mash Black Beans: In a medium bowl, mash the black beans with a fork until mostly smooth but with some texture.
4. Sauté Vegetables: In a skillet, heat the olive oil over medium heat. Add the onions, garlic, and bell peppers, and sauté until soft, about 5-7 minutes.
5. Combine Ingredients: In a large mixing bowl, combine the mashed black beans, sautéed vegetables, grated carrots, cooked quinoa, cumin, chili powder, salt, pepper, and shredded cheese (if using). Stir everything until well mixed.
6. Form Patties: With wet hands, shape the mixture into burger patties. You should yield around 6-8 patties, depending on your size preference.
7. Bread the Patties: Place the breadcrumbs in a shallow dish. Gently coat each patty in the breadcrumbs, ensuring they are well-covered.
8. Bake: Arrange the patties on the prepared baking sheet. Bake for 20-25 minutes, flipping halfway through, until golden brown and crispy.
9. Cool Slightly: Remove from the oven and let them cool slightly before serving. This will help the patties hold together better.
