  4. Grease the slow cooker and transfer the browned beef mixture into it.
  5. Scatter the diced peppers over the beef and stir to combine evenly.
  6. Pour in the diced tomatoes, tomato sauce, and beef broth, stirring until well combined.

  8. Cover and set to cook on LOW for 4–5 hours or HIGH for 2–3 hours until tender.
