Combine sweet potatoes, black beans, bell pepper, onion, and garlic in a bowl. Drizzle with olive oil and season with cumin, paprika, chili powder, salt, and pepper.
Transfer mixture to a casserole dish, cover with foil, and bake for 30-35 minutes until tender.
Remove foil, sprinkle cheese on top, and bake uncovered for 10-15 minutes until melted and bubbly.
Garnish with cilantro, serve with lime wedges, and add optional toppings as desired.
