I have made this many times for a Super Bowl get together. I serve the chili mixture in a medium crockpot to keep warm, serve the onions, sour cream, green peppers and cheese and whatever else you want to serve, on the side in large bowls, hollow out the buns, cover with plastic wrap and place the buns on a plate, and let everyone make their own "chili bowl"! The ingredients listed are just the basics to the chili recipe, of coarse you can add in other ingredients as desired. The amounts stated are good for up to 8 sandwiches, you double the recipe to serve more. The chili is best made a day ahead and refrigerated, just warm over the stove before serving.
