Sautee green pepper, garlic, and onion in olive oil until onions turn translucent.
Add the ground beef to the vegetables and cook until all of the meat is browned. Drain some of the grease, but leave a little for flavor.
Add the rest of the ingredients: diced tomatoes, kidney beans (liquid and all), tomato sauce, and chili seasoning packet. If you prefer your chili spicier, feel free to add some chili powder!
Chili is best after simmering for awhile, but you can enjoy immediately!
