Step 1

Slice flank steak against the grain, on an angle into 1/4-inch thin slices. Transfer to a medium bowl. Tip: to easily slice beef thinly, freeze the exposed beef for 40 minutes until the exterior is hard to touch and slice with a sharp knife.

Step 2

Marinate beef with Marinade ingredients as listed above. Marinate at room temperature for 15-20 minutes.

Step 3

In a small bowl, combine Sauce ingredients as listed above. Set aside.

Step 4

In a large skillet on low heat, heat vegetable oil. Stir fry white onions and scallion whites for 30 seconds. Remove and set aside.

Step 5

Increase to medium high heat, add marinated beef in a single layer and spread apart. Brown beef on each side for 2-3 minutes per side.

Step 6

Reduce to medium heat, pour prepared sauce in a circular motion, and stir fry for another 30-60 seconds until sauce thickens.

Step 7

Toss back in garlic, scallion greens, and cooked onions from before. Stir fry for another 30-60 seconds. Remove off heat and enjoy with a bowl of plain rice and your favourite vegetables!
