Steam bake the sweet potatoes. Let cool a few minutes, before opening and smashing.
Prepare the mango-black bean salsa. Cut the mango, and toss into a mixing bowl. Mix in the drained black beans, green peppers and chopped red onion. Sprinkle the lime juice, cumin, cinnamon and salt over top and toss gently.
Once the sweet potatoes are smashed and ready, add butter if you like, and then top with the mango-black bean salsa.
Serve Stuffed Sweet Potatoes with Mango-Black Bean Salsa as is, or with a side of bread or veggies.
