Add the beef to a skillet over medium-high heat and break it up with your spoon as you go along until it's cooked (approx. 8-10 minutes). If there's a lot of excess fat, drain it.

Take the pan off the heat and stir in the sauce ingredients hoisin sauce, soy sauce, sriracha, ginger, and garlic.

Reduce the heat to medium and return the pan to the heat. Add the red pepper pieces. Cook for a few more minutes, stirring often, until the peppers are tender-crisp.

Serve the beef over the rice or cooked cabbage and garnish as desired.
