Instructions

  1. Step 1: Heat 1 tbsp olive oil and 2 tbsp sesame oil in a large wok or skillet over high heat until shimmering, about 1 minute.
  2. Step 2: Add 1 lb thinly sliced beef sirloin strips and stir-fry for 3-4 minutes until browned but still tender. Remove beef from pan and set aside.
  3. Step 3: In the same pan, add 1 tbsp finely grated fresh ginger and 2 minced garlic cloves. Stir-fry for 30 seconds until fragrant.
  4. Step 4: Add 1 medium julienned red bell pepper and 1 medium sliced zucchini half-moons to the pan. Stir-fry for 4-5 minutes until vegetables are crisp-tender.
  5. Step 5: Return beef to the pan along with 3 tbsp soy sauce (or coconut aminos), 1 tbsp rice vinegar, 1/4 tsp red chili flakes, and 1/2 tsp black pepper. Toss everything together and cook for another 2 minutes until sauce thickens slightly and coats the beef and vegetables.
  6. Step 6: Remove from heat and garnish with 2 sliced green onions and 1 tbsp toasted sesame seeds. Serve hot for a flavorful keto-friendly dinner.
