Creating Crispy Chilli Beef Rice is straightforward if you follow these easy steps:

1. Prep the Beef: In a bowl, combine the sliced beef, soy sauce, and a pinch of salt and pepper. Marinate for 10 minutes.
2. Coat the Beef: In a separate bowl, mix cornflour and all-purpose flour. Coat each slice of marinated beef in this flour mixture.
3. Heat Oil: In a large skillet or wok, heat the oil over medium-high heat until hot.
4. Fry the Beef: Carefully add the coated beef slices to the hot oil. Fry until crispy and golden brown, about 3-4 minutes. Remove and place on paper towels to drain excess oil.
5. Sauté Vegetables: In the same skillet, remove excess oil, leaving about 1 tablespoon. Add garlic and ginger, sautéing until fragrant.
6. Add Peppers: Toss in the red and green bell peppers, stirring for about 2 minutes until slightly tender.
7. Make the Sauce: Mix together the oyster sauce, chili sauce, and sesame oil in a small bowl. Pour this over the sautéed vegetables.
8. Combine Beef and Rice: Add the crispy beef back into the skillet along with the cooked jasmine rice. Stir until everything is well combined and heated through.
9. Garnish: Finally, stir in the chopped green onions for freshness. Adjust seasoning if necessary.
10. Serve Warm: Transfer the Crispy Chilli Beef Rice to individual plates or a serving dish.
