How to Make It
In a large skillet, cook ground beef, onion, bell pepper, and garlic over medium-high heat. Stir until beef crumbles and is no longer pink. Once cooked, drain mixture.
Place cooked mixture in a 5-quart slow cooker. Stir in beans, diced tomatoes, chili powder, pepper, salt, and ground cumin. Cook at HIGH 3 to 4 hours or at LOW 5 to 6 hours. To thicken consistency, stir in finely crushed saltine crackers until the desired thickness is achieved.
