Ingredients

Scale

Beef Marinade

  • 1 lb Lean Flank Steak, thinly sliced
  • 1 tbsp Low-Sodium Soy Sauce
  • 1 tbsp Cornstarch

Vegetables and Aromatics

  • 4 cups Baby Bok Choy, sliced (separate stems and leaves)
  • 1 medium Red Bell Pepper, sliced
  • 3 cloves Garlic, minced
  • 1 tbsp Fresh Ginger, grated

Sauce

  • 2 tbsp Low-Sodium Soy Sauce
  • 2 tbsp Rice Vinegar
  • 1 tbsp Sesame Oil
  • 1/2 cup Water
  • 1 tbsp Hoisin Sauce (optional)
  • 1 tbsp Sriracha (optional, adjust to taste)

Finishing Touches

  • 1 spray Cooking Spray or equivalent olive oil
  • 2 tbsp Green Onions, chopped (for garnish)
  • 1 tbsp Sesame Seeds (for garnish)

Instructions

  1. Marinate the beef: Toss the thinly sliced flank steak with 1 tablespoon of soy sauce and 1 tablespoon of cornstarch. Let it sit for about 5 minutes to absorb the flavors and help tenderize the meat while you prepare the sauce.
  2. Prepare the sauce: In a bowl, whisk together the remaining 2 tablespoons of soy sauce, 2 tablespoons rice vinegar, 1 tablespoon sesame oil, 1/2 cup water, 1 tablespoon hoisin sauce (if using), and 1 tablespoon sriracha (adjust based on spice preference).
  3. Cook aromatics: Heat a large skillet over high heat and spray with cooking spray. Add minced garlic and grated ginger to the hot pan, stir-frying for about 30 seconds until fragrant, being careful not to burn them.
  4. Cook the beef: Add the marinated beef to the skillet. Stir-fry for 2-3 minutes until browned but still tender. Remove the beef from the skillet and set aside to prevent overcooking.
  5. Stir-fry vegetables: Spray the skillet again lightly and add bok choy stems and red bell pepper slices. Stir-fry for about 2 minutes to soften the stems slightly. Then add bok choy leaves and continue to stir-fry for another 1-2 minutes until they are wilted but still vibrant.
  6. Combine and simmer: Return the cooked beef to the skillet with the vegetables. Pour the prepared sauce over the ingredients and stir well to coat everything evenly. Let it simmer for 1-2 minutes until the sauce thickens and becomes glossy.
  7. Garnish and serve: Remove from heat. Garnish with chopped green onions and sesame seeds. Serve hot over cauliflower rice for a low-carb option or brown rice for a heartier meal.

Notes

  • For a gluten-free version, substitute tamari for soy sauce and arrowroot powder for cornstarch.
  • To reduce sodium, use low-sodium soy sauce and omit hoisin sauce if desired.
  • Protein swaps: use chicken, shrimp, or tofu instead of flank steak for different dietary preferences.
  • If you like it spicier, increase the amount of sriracha or add chili flakes.
  • Make sure not to overcook the bok choy to keep it crisp and fresh.
