Customization & Variations
While flank steak is excellent here, you can easily adapt this dish. Consider swapping the beef for thinly sliced chicken breast or firm tofu for a different protein. Feel free to use a mix of bell pepper colors—red, yellow, or orange—to add even more visual appeal and varied sweetness. If you're out of rice vinegar, a similar amount of apple cider vinegar can work as a suitable substitute in a pinch, though the flavor will be slightly different.
This Instant Pot Pepper Steak is perfect for a busy weeknight dinner or a relaxed weekend meal. Serve it over a bed of steamed white or brown rice to soak up every drop of that delicious sauce, creating a complete and satisfying meal.
