Follow these simple steps to create your Keto Beef Stir-Fry:

1. Marinate the Beef: In a bowl, combine the sliced beef with soy sauce and sesame oil. Let it marinate for 15 minutes.
2. Prep the Vegetables: While the beef marinates, wash and slice your vegetables. Set them aside.
3. Heat the Oil: In a large skillet or wok, heat olive oil over medium-high heat.
4. Cook the Beef: Add the marinated beef to the skillet and cook for 2-3 minutes, stirring frequently until browned. Avoid overcrowding the pan; you may need to do this in batches.
5. Add Garlic and Ginger: Once the beef is nearly done, add minced garlic and ginger. Stir for another 1-2 minutes until fragrant.
6. Add Vegetables: Toss in the bell pepper, broccoli, and snap peas. Stir-fry for approximately 3-5 minutes, or until vegetables are tender yet crisp.
7. Finish the Dish: Season with salt and pepper to taste. Add chopped green onions and give everything a final toss.
8. Serve: Remove from heat and transfer to a serving platter. Drizzle with extra sesame oil if desired and sprinkle sesame seeds over the top.
