Sprinkle the beef with the cooking wine and baking soda and set aside at room temperature for 15 minutes.
While the beef marinates, prepare the sauce by combining all sauce ingredients in a bowl. Set aside.
Heat a large nonstick pan over medium-high heat. When hot, add half the oil and the broccoli. Cook on high heat until light charred, stirring occasionally, 5-7 minutes. Add a tablespoon or two of water and cover with a lid to steam to desired consistency, about 1-2 minutes. Transfer to a plate and set aside.
Add the remaining half of the oil and the beef, cooking in a single layer and turning once, about 4-5 minutes total. Add the sauce and cook until reduced and thickened. Stir in the broccoli and off heat, drizzle with toasted sesame oil.
Notes
Freezing the steak for 30 minutes can help it stay firm, which makes slicing much easier. You can also ask your butcher to slice it for you for even easier prep. Often times, Asian markets will sell beef pre-sliced as well.Protein:Energy Quotient [calories]: 1.26
