Preheat large non-stick skillet on high heat and add ground turkey. Cook until brown, stirring and breaking into small pieces with spatula, occasionally. Transfer to a large crockpot. If using leftover cooked turkey, skip the browning step.Return skillet to medium heat and spray with cooking spray. Add garlic, onion, celery, bell peppers and saute for 5 minutes or until golden brown. Transfer to a slow cooker.Add remaining ingredients to slow cooker, cover and cook 8 hours on Low or 4 hours on High. Reduce cooking time to 5 hours on Low and 3 hours on High, if using cooked turkey. Serve hot. Chili tastes even better the next day. This chili is mild enough for the kids. Add more heat with extra chili powder, Taco seasoning, diced green chiles or jalapenos.
