Brown the turkey: In a large skillet over medium heat, cook the ground turkey until it’s no longer pink. Break it apart with a spoon as it cooks. Drain any excess fat.
Add aromatics: Stir in diced onion and garlic, cooking for 2–3 minutes until fragrant and softened.
Transfer to the slow cooker: Add the cooked turkey mixture to your slow cooker.
Add remaining ingredients: Stir in diced bell peppers, beans, tomatoes, tomato sauce, tomato paste, chicken broth, and all the spices. Mix well to combine.
Slow cook: Cook on Low for 6–8 hours or High for 3–4 hours. Stir occasionally if possible, allowing flavors to meld beautifully.
Adjust seasoning: Before serving, taste and adjust salt, pepper, or spices as desired.
