Chop the onion and bell pepper, and mince the garlic.

In a skillet over medium heat, brown the ground beef until fully cooked. Drain excess fat.

In the crockpot, combine the cooked ground beef, chopped onion, bell pepper, minced garlic, kidney beans, black beans, pinto beans, diced tomatoes, chili powder, cumin, salt, black pepper, paprika, and beef broth.

Cover and cook on low for 8 hours or on high for 4 hours.

Once cooked, stir well and serve hot. Enjoy with toppings like cheese, sour cream, or green onions if desired.
