In a small bowl, mix together both chili powders, onion powder, garlic powder and pepper. Set it aside for a moment.
Heat the oil in a large skillet over medium high heat. Add the ground turkey and cook until brown but still a little pink. Break the turkey into small pieces as it cooks.
Stir the spices in with the turkey and cook for another 2 minutes or until the spices are fragrant.
Place the turkey into the bottom of the slow cooker.
To the slow cooker add the diced tomatoes, beans, and tomato paste. Stir.
Then stir in the carrots and mushrooms.
Tightly place the lid onto the slow cooker and set the cooking time for 8-10 hours on low or high 5-6 hours.
Stir in the salt and lime juice. Serve hot with your favorite chili toppings and tortilla chips. We love sour cream or plain greek yogurt, avocado, cilantro, sliced jalapenos, and shredded cheddar cheese.
