Ingredients

Instructions

  1. Step 1: Heat 1 tbsp sesame oil in a large wok or skillet over high heat until shimmering. Add 12 oz thinly sliced flank steak and stir-fry for 2-3 minutes until browned but not fully cooked. Remove steak and set aside.
  2. Step 2: Add remaining 1 tbsp sesame oil to the pan, then add 4 cups cauliflower florets. Stir-fry for 4-5 minutes until cauliflower is bright and slightly tender but still crunchy.
  3. Step 3: Return steak to the pan with cauliflower. Add 3 cloves minced garlic and 1 tbsp minced fresh ginger, stirring for 30 seconds until fragrant.
  4. Step 4: Pour in 3 tbsp soy sauce, 1 tbsp rice vinegar, and 1/4 tsp red pepper flakes. Stir-fry for another 2 minutes until sauce coats the beef and cauliflower and thickens slightly.
  5. Step 5: Remove from heat and garnish with 2 thinly sliced green onions and 1 tbsp toasted sesame seeds if desired. Serve hot for a flavorful keto stir-fry.
