Sauté onions peppers and mushroom slices.

Slice up your roast into long thin strips. Once onions and peppers begin to soften up and have cooked a bit add the roast beef strips. (If you have leftover cooked steak it works well too.)

Now add your hoisin sauce, oyster sauce, Worcestershire sauce and BBQ sauce and ensure to mix well so everything is nicely covered. You may add 1/4 cup of water if needed however it most likely wont be necessary peppers and mushrooms have a lot of moisture.

Add leftover roast beef strips to pan as well as sauces.

Season with mix of spices. Because the meat was seasoned in it’s original cooking process not much seasoning is required now.

    This is a great plan for use of that leftover meat, could really be anything, chicken, beef or pork. Love this recipe and I will add it to my weekly meal planning. I love when I can plan for more than two days in a row! Seriously, not good at it.
