Add the onion, pepper, tomatoes, mushrooms and soy sauce.
Cover and cook on LOW for 7 to 8 hours, until the beef and vegetables are tender.
Serve over cooked rice, if desired.

You can add garlic powder, paprika, or even a pinch of red pepper flakes to customize the flavor according to your taste preferences.- Adjusting the thickness of the sauce: If you prefer a thicker sauce, you can mix a tablespoon of cornstarch with a little water and add it to the slow cooker during the last hour of cooking.
