It doesn't get any more convenient for tailgating than eating chili and corn chips straight out of the bag. But, if you have a comfy seat to watch the game, serving chili over spaghetti is the way to go.
Technique tip: Toasting the spices in the pan before adding the meat and liquids really brings out all the aroma and flavor and adds a depth that you wouldn't get otherwise.
Swap option: Try ground turkey for a lower calorie chili, or even go vegetarian with crumbled firm tofu instead of meat.
In a large pot, heat up the olive oil on medium heat. Add the onion and garlic, and sauté until the onion is translucent.2.
Add all of the spices, salt and pepper and cocoa powder and stir to combine. Cook for 5 minutes, allowing the spices to toast up and release their aroma. Pour the water in the pan and use a wooden spoon to loosen the cooked spices from the bottom of the pan.3.
Add the meat to the pan and stir to combine. Sauté until the meat is browned through.4.
Add the tomato sauce and rice vinegar, stir to combine. Reduce the heat to low, cover and simmer the chili for 1½ hours, stirring every 5-10 minutes (if you want to use a slow cooker, pour the complete mixture into your slow cooker after adding the tomato sauce and vinegar and set it on high for 3 hours).5.
When the chili is done cooking, you have a choice of serving styles. You can go the true Cincinnati 3-way, or take it West Coast and pour it over corn chips. For the Cincinnati 3-way, pour the chili over cooked spaghetti and top it generously with shredded cheddar cheese and diced onions. For West Coast, pour the chili directly in the bag of chips along with the cheddar cheese and onions and eat it right out of the bag.
