Stir Fry:
Stir fry the vegetables – Heat 1 tbsp oil in a wok or frying pan over high heat. Once the oil is hot, add onion and bell peppers. Stir fry for about 30 seconds. Transfer to a separate bowl.

Sear the beef – Add 2 tbsp oil to the wok. Once the oil is hot, sear the marinated beef for a few minutes on each side. Don't overcrowd the pan. You may need to cook the beef in 2-3 batches. Transfer to a separate bowl.

Cook the sauce – Add 1 tbsp oil to the wok. Add garlic and stir fry until fragrant. Pour in the sauce and cook until simmering and the sauce thickens. Taste the sauce and adjust the seasonings.

Assembly – Add the cooked beef, onion, and bell peppers back into the wok. Toss in the sauce until well combined.

Serve hot with steamed rice.
