Add minced garlic and diced bell pepper, stirring for 2-3 minutes until softened.
Push vegetables to the sides and add ground turkey in the center. Cook until browned, about 6-8 minutes.
Stir in chili powder and cumin, cooking for about one minute.
Add canned tomatoes, mixed beans, and water or broth. Season with salt and pepper.
Bring to a gentle boil, then reduce heat to low and cover. Let simmer for at least 30 minutes, stirring occasionally.
Taste and adjust seasoning if necessary. Let sit for 5 minutes before serving.
Notes
Consider adding toppings like shredded cheese, diced green onions, or sour cream. This chili can be made ahead of time and tastes even better the next day.
