Make a hearty and flavorful beef and black bean chili using your food processor. Start by pulsing onions, garlic, and bell peppers in the food processor until finely chopped. In a large pot, brown the ground beef and then add the chopped vegetables. Cook until the vegetables are softened. Add canned black beans, diced tomatoes, beef broth, and spices such as chili powder, cumin, and paprika. Let the chili simmer for about 30 minutes to allow the flavors to meld together. Serve with your favorite toppings like shredded cheese, sour cream, and chopped green onions.
