2Add the beef, green bell pepper, red bell pepper, onion, and garlic.
3In a bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, cornstarch, black pepper, garlic powder, onion powder, ground ginger, and olive oil until smooth.
4Pour over the beef and vegetables.
5Cover and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the beef is tender and the sauce has thickened.
6Stir well before serving so the beef and peppers are coated in the sauce.
7Sprinkle with parsley if using, then serve hot over rice or mashed potatoes.
8Store leftovers in the fridge for up to 3 days.
