Chili and spaghetti sauce have so much in common. They both have tons of tomatoes, ground beef that's often added, and lots of herbs and spices thrown in. So, it makes sense that you would top your spaghetti with chili, as in the recipe that follows, when you want something a little different. It's easy to do, and you don't have to wait until you have all that leftover chili after a night of feasting.
Unlike traditional chili, this recipe uses a quick chili that comes together in the pan in about 20 minutes. While that's going, you simply boil your pasta so when it's done, all you need is to bring the two together. When the dish is finished, it gets topped with lots of cheddar cheese, because these are chili flavors and chili calls for cheddar.
