Preheat your oven to 350°F (175°C).

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onions and bell peppers, cooking for 5–7 minutes until softened.

Add 1 pound of ground turkey to the skillet. Cook for 8–10 minutes until browned and no longer pink.

Stir in 1 teaspoon each of garlic powder, onion powder, paprika, salt, and pepper. Mix well for 2 minutes.

In a baking dish, layer 2 cups of cubed sweet potatoes, then top with the turkey and vegetable mixture.

Optional: Sprinkle 1 cup of shredded cheese over the top.

Cover with aluminum foil and bake for 25 minutes.

Remove the foil and bake for an additional 10 minutes until the sweet potatoes are soft and cheese is golden.

Let the casserole cool for a few minutes before serving.
