Serving Steak Stir Fry

If you’re watching your carbohydrates, serve the pepper steak stir-fry as-is or on top of a bed of cauliflower rice (you can find it frozen at Trader Joe’s or easily whip it up by popping cauliflower in a food processor and pan-frying it in butter or oil until lightly crisped). Otherwise, serve it atop some steamed white rice or quinoa, or tossed into your favorite rice noodles. 

Best Way to Store Your Leftovers 

To keep pepper steak stir fry on hand for up to 5 days, store it in an airtight container in the fridge. This will keep the beef from drying out and will also help it to continue marinating in itself – making for some pretty incredible leftovers.

Reheating Tip: Reheat leftover pepper steak stir fry in the microwave for a couple of minutes or until warmed through. Avoid reheating it in the skillet, as it’s super easy to overcook the steak and turn it rubbery.
