Instructions

  1. Step 1: Heat 2 tablespoons vegetable oil in a large wok or skillet over high heat until shimmering.
  2. Step 2: Add 1 pound thinly sliced flank steak and stir-fry for 3-4 minutes until browned but still tender. Remove beef and set aside.
  3. Step 3: In the same wok, add 3 minced garlic cloves, 1 tablespoon grated ginger, 1 large sliced red bell pepper, 1 large sliced green bell pepper, and 1 medium sliced yellow onion. Stir-fry for 4-5 minutes until vegetables are crisp-tender.
