Sure! You obviously won’t need to marinate it ahead of time. Instead, you’ll saute the veggies, remove them from the pan, brown and crumble the ground beef, remove it from the pan, then add all of the sauce ingredients to the skillet, bring the sauce to a boil, and then thicken with cornstarch. Everything heads back into the skillet once the sauce is nice and thick, and voila! you’ve got ground beef stir fry!
