6. Combine Ingredients: Return the cooked beef to the skillet. Pour in the soy sauce, sesame oil, rice vinegar, black pepper, and red pepper flakes (if using).
7. Stir-Fry: Stir everything together, cooking for an additional 2-3 minutes until the sauce thickens slightly.
8. Garnish: Remove from heat and sprinkle with chopped green onions and sesame seeds.
9. Serve Hot: Enjoy your Keto Beef and Broccoli Stir-Fry hot.
