In a large pot over medium heat, heat the oil. Stir in the onion, bell pepper, and garlic. Cook 5 minutes, or until the onions become translucent. Add the turkey and cook until lightly browned. Drain, if needed. Stir in chili powder, cumin, salt, and oregano.
Add the broth, tomatoes, beans, and corn, if using. Bring to a boil and reduce the heat to low. Simmer at least 30 minutes, but the longer the better. Adjust seasonings, as needed.
Ladle into bowls and top with your favorite toppings to serve.
Crockpot: Simply follow the instructions up until adding the seasonings. Then place the remaining ingredients in the slow cooker with the cooked turkey. Cook on high for 3-4 hours or on low for 6-8 hours.Variations:
Use ground beef in place of ground turkey.
Make the spices your own by adding smoked paprika, turmeric, garam marsala, or whatever sounds good to you.
Add some heat with cayenne pepper or crushed red pepper flakes.
