Place the thinly sliced flank steak (or sirloin), sliced red bell pepper, sliced green bell pepper, sliced small onion, and minced garlic into the crockpot.

In a separate medium-sized bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, and black pepper until well combined. This will form your savory sauce.

Carefully pour the prepared sauce evenly over the beef and vegetables in the crockpot, ensuring everything is adequately coated.

Cover the crockpot with its lid. Cook on the LOW setting for 6 to 7 hours, or on the HIGH setting for 3 to 4 hours, until the beef is fork-tender.

Approximately 20 minutes before the end of the cooking time, in a small bowl, whisk together the cornstarch and 2 tablespoons of water to create a smooth slurry.

Stir the cornstarch slurry into the crockpot with the beef and vegetables. Mix thoroughly to distribute the thickener.

Continue to cook, uncovered, for the remaining 15-20 minutes, or until the sauce has thickened to your desired consistency.

Serve the Crockpot Pepper Steak hot over a bed of warm rice or noodles. Garnish with chopped green onions, if desired, before serving.
