Classic chili is made in the crockpot with chunks of beef, lots of tender beans, tomatoes, onions, and spices. This recipe isn't technically "Classic, " Because true chili doesn't contain beans. But it is a classic in every other way. The slow cooker is a great way to make chili. The long cooking time makes all of the vegetables very tender, and the flavors blend beautifully. Serve this chili with some sour cream and guacamole to cut the heat, along with a green salad tossed with sliced mushrooms, and some icy cold beer or iced tea.
