Preparing vegetarian enchiladas is a straightforward process that doesn’t require extensive culinary skills. Follow these simple steps to create a dish that will impress your family and friends:

1. Preheat the oven to 375°F (190°C).
2. Prepare the filling: In a pan, heat olive oil over medium heat. Add diced bell peppers and cook until they are soft, about 3-5 minutes.
3. Add the remaining vegetables and spices: Stir in the black beans, corn, spinach, cumin, and chili powder. Season the mixture with salt and pepper to taste. Cook for an additional 5 minutes, allowing the flavors to meld together.
4. Warm the tortillas: To make them pliable, warm the tortillas in a microwave or on a pan for 15-20 seconds.
5. Assemble the enchiladas: Spoon the vegetable mixture onto each tortilla. Roll them up tightly and place them seam-side down in a baking dish.
6. Add sauce and cheese: Pour the enchilada sauce evenly over the rolled tortillas. Sprinkle shredded cheese on top to cover the enchiladas completely.
7. Bake: Place the baking dish in the preheated oven and bake for 20 minutes, or until the cheese is melted and bubbly.
8. Serve hot: Once baked, remove the enchiladas from the oven and let them cool slightly before serving.
