This is an all-meat, no-bean chili that is a snap to fix and cook in a crock pot. The fact that the recipe is a simple, no-frills combination lends it to all kinds of possible variations. Add some chopped onions and bell pepper to the skillet along with ground beef, or add some chile peppers or extra cayenne. The stewed tomatoes add texture and flavor, but crushed tomatoes, fire-roasted, or chili-seasoned tomatoes would be excellent choices as well. See the variations section below the recipe for some serving and garnishing ideas and suggestions for additional ingredients.
