In a slow cooker on the lowest to medium setting, add the ground beef, tomato sauce, tomato paste, tomatoes, beans, and all the spices including the chil mix. Let cook several hours, check always to make sure the meat is fully cooked. Better results of flavor if it cooks for 4-6 hours.
Here is the fun part. Scoop 1 1/2 cup into a soup bowl or table bowl, put 1/3 cup of cheese in the center, and add your scoops around the bowl in a petal format. Once put together, top with your diced onions.
