This ground beef chili is a snap to prepare with canned beans and tomatoes, and the crock pot makes it a breeze to cookbell peppers, chopped onion and celery, and chili powder add texture and flavor to this chili. Add heat to the dish with some cayenne pepper, or add some chopped fresh or canned jalapeno peppers or another type of fresh, hot chile pepper. Chili is one of those dishes that is very adaptable. If the chili seems too mild in flavor, add more chili powder or some ground cumin. If you like chunks of tomatoes, make it with diced tomatoes instead of the crushed tomatoes. Substitute black beans, pinto beans, or small red beans for the kidney beans. A combination of two parts ground beef and one pound ground pork or pork sausage are some other variations that can add flavor. Ground turkey thighs are a tasty alternative as well, especially if you like to avoid red meat. See the tips and variations for a variety of ways to thicken the chili along with some additional flavor ideas.
