Instructions

  1. Step 1: Heat 1 tbsp sesame oil in a large skillet or wok over high heat until hot but not smoking. Add 10 oz thinly sliced beef sirloin and stir-fry for 3-4 minutes until browned but still tender. Remove beef and set aside.
  2. Step 2: In the same skillet, add remaining 1 tbsp sesame oil, 3 minced garlic cloves, and 1 tsp grated fresh ginger. Stir-fry for 30 seconds until fragrant.
  3. Step 3: Add 1 medium thinly sliced red bell pepper and cook for 2 minutes until crisp-tender.
  4. Step 4: Stir in 4 cups grated cauliflower rice, 3 tbsp soy sauce, 1/2 tsp salt, and 1/4 tsp black pepper. Cook for 5-6 minutes, stirring frequently until cauliflower is tender but not mushy.
  5. Step 5: Return beef to the skillet, add 2 chopped green onions, and toss everything together for 1 minute to combine and heat through.
  6. Step 6: Sprinkle 1 tbsp toasted sesame seeds over the top before serving.
