Creating the amazing Crispy Chilli Beef Rice is straightforward when you follow these simple steps:

1. Marinate Beef: In a bowl, combine the sliced beef with soy sauce and oyster sauce. Let it marinate for about 10 minutes.
2. Coat Beef: Add cornstarch to the marinated beef. Ensure all pieces are evenly coated. This will help achieve that desired crispy texture.
3. Heat Oil: In a pan, heat the vegetable oil over medium-high heat until hot enough for frying.
4. Fry Beef: Carefully add the beef to the hot oil, ensuring not to overcrowd the pan. Fry until the beef is golden brown and crispy, about 3-4 minutes. Remove and set on a paper towel to drain excess oil.
5. Sauté Vegetables: In the same pan, add the sliced red chillies, onion, bell pepper, garlic, and ginger. Sauté for 2-3 minutes until the vegetables are tender and aromatic.
6. Combine Ingredients: Add the crispy beef back into the pan, mixing with the sautéed vegetables. Drizzle sesame oil over the mixture for added flavor.
7. Add Rice: Gently fold in the cooked rice, ensuring it is well combined with the beef and vegetable mixture. Stir-fry for about 3-4 minutes or until heated through.
8. Garnish: Finally, add the sliced green onions on top and season with salt and pepper to taste.
9. Serve Hot: Transfer the Crispy Chilli Beef Rice to a serving dish and be prepared for applause!
