Preheat the oven to 425°
Place bell pepper wedges in a bowl and toss with oil, salt, black pepper, cumin, chili powder, and garlic powder. You may need to use your hands to evenly coat.
Place the wedges on a baking sheet in one even layer and bake for 10 minutes. Then set aside.
Meanwhile, in a large pan, heat 1 Tbsp oil over medium heat. Add black beans, stir, and cook until heated through, about 2-3 minutes.
Stir in taco seasoning and water. Bring to a boil, reduce heat, and let simmer for 5 minutes or until thickened.
Fill bell pepper wedges with the bean mixture and then top with cheese. Bake for 10 minutes or until bubbly and cheese is melted.
Top with desired toppings and enjoy!
