Preheat oven to 425°F. Arrange sweet potatoes on a baking tray that has been lined with foil. Pierce with a fork and roast for one hour in the oven, or until soft.
While the sweet potatoes are cooking, spray a large skillet with cooking spray and add in onion and peppers. Cook for about 5 minutes over medium to high heat and until soft. Add in preferred Meal Starter, black beans and seasonings; continue cooking until all ingredients are completely coated in the seasonings.
Remove the sweet potatoes from the oven; allow them to cool for about 5 minutes until they are just warm enough to handle; slice in half. Use a large spoon to remove the inside, leaving about 1/4 inch around the inside of the skin. Transfer inside to a medium-sized mixing bowl. Set the skins aside.
Add the Meal Starter mixture and lime juice to the sweet potato in the bowl; stir until completely combined.
Arrange the skins on the same baking pan, and stuff them with the Meal Starter sweet potato mixture. Sprinkle with cheese and bake at 425°F. for 15 minutes.
Serve, topped with fresh cilantro, lime wedges, avocado pieces and salsa. Enjoy!
