Ingredients

  • 400 g Beef sirloin (thinly sliced)
  • 2 large Bell peppers (mixed)
  • 150 g Broccoli florets
  • 3 tbsp Soy sauce
  • 3 cloves Garlic (minced)
  • 1 tbsp Sesame oil
  • 1 tsp Cornstarch

Instructions

  1. 1
    Marinate beef

    Toss sliced beef with 1 tbsp soy sauce and cornstarch. Let rest 5 minutes while you prep vegetables.

  2. 2
    Sear beef

    Heat oil in a wok over high heat. Sear beef in batches for 2 minutes per side until browned. Remove and set aside.

  3. 3
    Stir-fry vegetables

    Add sesame oil, broccoli, and bell peppers. Stir-fry 3-4 minutes. Add garlic and remaining soy sauce.

  4. 4
    Combine

    Return beef to the wok, toss everything for 1 minute. Serve immediately over steamed rice.

Notes

  • Slice beef against the grain and as thin as possible — freeze for 20 minutes first for easier slicing.
  • Cook in batches to avoid overcrowding — this ensures proper searing.
  • Add the sauce around the edges of the wok, not directly on the food, for better caramelization.

This recipe has 450 calories with 36g protein per serving without rice. Adding a cup of steamed rice brings it to about 650 calories.

Can I use a regular pan instead of a wok?

Yes, but use your largest skillet. The key is HIGH heat and not overcrowding. Cook in small batches to achieve proper searing rather than steaming.
