Beef chili is a hearty and comforting dish that is perfect for chilly days. Brown ground beef in a pot, then add onions, garlic, and spices like chili powder, cumin, and paprika. Stir in diced tomatoes, tomato sauce, and kidney beans. Simmer for a while to let the flavors meld together. Serve with toppings like shredded cheese, sour cream, and chopped green onions.
