Pierce sweet potatoes with a fork. Wrap in a damp towel and microwave for 6 minutes or until soft.
Let cool. Cut sweet potatoes in half and scrape out flesh. Bake for 10 minutes.
In a small bowl, mix together black beans, ground cumin, chili powder, paprika, salt and pepper.
Remove from oven. Spoon black bean mixture into sweet potato halves, top with diced tomatoes and green chilies, sprinkle shredded cheese and bake another 5 minutes or until cheese melts.
Top each skin with optional toppings and serve right away!
Notes
*Season black beans with homemade or store bought taco seasoning.
