This hearty chili is perfect for a cold winter day. Pulse some onions, garlic, and chili peppers in a food processor, then brown the ground beef in a large pot. Add the onion mixture, canned tomatoes, beef broth, and your favorite beans (such as kidney or black beans), and let simmer for at least an hour to allow the flavors to meld together. Serve with shredded cheese and sour cream for a comforting meal.
