This classic comfort food is made even easier with the help of a food processor. Simply pulse the onion, garlic, and peppers until finely chopped, then add to the crockpot with the ground beef, beans, tomatoes, and seasonings. Let it cook on low for 6-8 hours, then top with your favorite garnishes, such as shredded cheese, sour cream, and green onions. It's a hearty and flavorful meal that's perfect for a chilly evening.
