While the oven is heating, scrub the sweet potatoes thoroughly and poke a few holes in them with a fork. Place them on a baking sheet and bake for 45-50 minutes, or until they are tender when pierced with a knife.
In a large skillet, heat the olive oil over medium heat. Add the diced onion and bell pepper, sautéing until they are softened, about 5-7 minutes.
Add the minced garlic to the skillet and cook for an additional minute until fragrant.
Stir in the ground turkey, breaking it apart with a spatula. Cook until browned and fully cooked through, about 7-10 minutes.
Add the black beans, cumin, smoked paprika, chili powder, salt, and pepper. Mix well and cook for another 2-3 minutes, allowing the flavors to meld together.
Once the sweet potatoes are done baking, carefully remove them from the oven and let them cool for a few minutes.
Slice each sweet potato in half lengthwise and gently scoop out a small portion of the flesh (be careful not to break the skin).
Fill each sweet potato half with the ground turkey mixture, then top with shredded cheese. Return them to the oven for an additional 10 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let cool slightly before garnishing with fresh cilantro or parsley. Serve with a dollop of Greek yogurt or sour cream.
Notes
Serve the stuffed sweet potatoes on a large platter, garnished with fresh herbs and a drizzle of Greek yogurt for a pop of color and flavor.
