Shaking beef

Method

1. 1 Slice the beef into 2.5 cm cubes, marinate with oyster sauce, soy sauce, sugar, and pepper for 15 minutes.
2. 2 Heat a pan until very hot, then add butter and crushed garlic and sauté until fragrant.
3. 3 Place the beef in a pan over high heat for 3 minutes, shaking the pan continuously to ensure the meat cooks evenly while remaining pink inside.
4. 4 Add the onions and bell peppers, stir quickly for 1 minute, then turn off the heat.
5. 5 Arrange the beef on a plate with lettuce and sliced tomatoes, and serve with a bowl of salt, pepper, and lime dipping sauce.
