Prepare Sweet Potatoes: Add diced sweet potatoes to a microwave-safe plate, cover with a damp paper towel, and microwave on high for 5 minutes until tender.
Make Sauce: In a small bowl, combine sour cream and salsa to create a zesty sauce. Set aside.
Cook Ground Turkey: Heat a skillet over medium-high heat, add ground turkey, and cook for about 5 minutes until slightly pink. Drain excess fat if necessary.
Combine Ingredients: Add hot sweet potatoes, black beans, salt, chipotle chili powder, and cumin to the turkey. Stir for about 5 minutes until sweet potatoes are soft and turkey is cooked.
Add Cheese & Serve: Remove from heat, sprinkle cheese on top to melt, and finish with green onions, tomatoes, and sauce before serving.
