This hearty and flavorful chili is perfect for a crowd. Use a food processor to chop onions, peppers, and garlic, then sauté in the Dutch oven until tender. Add ground beef and cook until browned, then add canned tomatoes, kidney beans, and chili powder. Simmer for a few hours until the flavors have melded together. Serve with shredded cheese and a dollop of sour cream.
