Instructions
- 1
Slice flank steak against the grain at a 45-degree angle into 1/4-inch thick pieces. Transfer to a large mixing bowl. (Tip: To thinly slice beef easily, freeze it for 45-60 minute fully exposed and when the exterior is hardened, slice with a sharp knife).
- 2
Marinate sliced flank steak with the marinade ingredients as listed above for 15 minutes and set aside.
- 3
In a small bowl, combine the sauce ingredients as listed above and set aside.
- 4
Heat vegetable oil in a large pan on medium-high heat. Fry beef until cooked and slightly browned on the edges, about 2 minutes. Remove and set aside.
- 5
Fry onions and red bell peppers until crisp and slightly tender, about 30 seconds. Do not overcook.
- 6
Add the sauce and simmer to thicken, about 1 minute. Once thickened, add cooked beef and toss everything together. Enjoy!
