Heat olive oil in a large skillet over medium-high heat. Add ground turkey and cook until browned, breaking it apart. Remove and set aside.

In the same skillet, add onion and bell pepper. Cook until softened, then add garlic and stir until fragrant.

Add sweet potatoes, paprika, thyme, cumin, chili powder if using, salt, and pepper. Stir to coat.

Pour in broth and optional tomatoes. Cover and simmer until sweet potatoes are tender, about 12–15 minutes.

Return turkey to skillet and cook uncovered for 3–5 minutes until heated through and liquid reduces slightly.
