  • 2 tbsp water as needed
Sauce
  • ¼ cup low-sodium soy sauce
  • 2 tbsp water
  • 1 tbsp oyster sauce
  • 1 tbsp rice vinegar
  • 2 tsp brown sugar
  • 1 tsp toasted sesame oil
  • 2 garlic cloves minced

  1. Whisk the sauce ingredients in a small bowl.
  2. Toss the sliced beef with 1 tbsp soy sauce and 1 tbsp cornstarch.
  3. Heat a large skillet or wok over medium-high heat; add the oil.
  4. Sear the beef in a single layer 3-4 minutes total, then move to a plate.
  5. Add broccoli and 2 tbsp water, cover and cook 2-3 minutes until bright green and crisp-tender.

  7. Toss about 1 minute until glossy.

Notes

  • No long marinade needed.
  • Flank steak is preferred; slice against the grain.
  • Don't overcrowd the pan; cook in batches if doubling.
  • Fresh broccoli is preferred for texture.
  • Raw rice won't cook in 15 minutes; use pre-cooked or microwave rice to keep the total-meal promise.
