Tender Crock-Pot Pepper Steak: A Flavorful Slow-Cooked Delight

Slice the beef into thin strips, and cut the peppers and onion into even slices.
Assemble in the Crock-Pot:

Add the beef strips, bell peppers, onion, garlic, diced tomatoes, soy sauce, Worcestershire sauce, sugar (if using), ground ginger, and black pepper to the Crock-Pot. Stir to combine.
Slow Cook:

Cover and cook on low for 6-7 hours or on high for 3-4 hours, until the beef is tender.
Thicken the Sauce:

In a small bowl, mix the cornstarch with water or beef broth to create a slurry. Stir it into the Crock-Pot 30 minutes before the cooking time ends. Allow the sauce to thicken.
Serve:

Serve the pepper steak hot over steamed rice, noodles, or mashed potatoes.
