Preparation: Dice the red bell pepper and zucchini, slice the green onions, and cut the corn tortillas into small wedges. This ensures a smooth cooking process.
Cook the Beef: Heat a large skillet over medium-high heat, lightly coating it with cooking spray and olive oil. Add ground beef and cook, breaking it apart, until browned, about 5-7 minutes. Drain any excess fat.
Sauté Vegetables: Add the diced red bell pepper, zucchini, and the white/light green parts of the green onions to the skillet. Cook for about 5 minutes, until tender.
Add Spices and Sauce: Stir in chili powder, cumin, garlic powder, and oregano. Cook for 1 minute, then add enchilada sauce, stirring to combine.
Combine Ingredients: Stir in black beans and corn. Layer the tortilla wedges over the mixture, pressing them down slightly.
Top with Cheese: Sprinkle 1 cup of shredded cheese over the top, cover the skillet, and reduce the heat to low. Let it cook for 10 minutes until the cheese is melted. Add the remaining ½ cup cheese and broil for a few minutes if you prefer a crispy top.
