In a bowl, combine meat and remaining marinade ingredients. Marinate for either a few minutes (we know, we’ve been there), or up to overnight.
Heat up a sauté pan until very hot and grease it a bit. Add broccoli, sprinkle with salt, and cook until broccoli is a little golden at the edges but still bright green. Remove from pan.
Grease the pan again (the amount of oil you use is up to you. Unlike fried Chinese dishes, I don’t think this needs all that much). Remove meat strips from marinade and add to hot pan. Cook until cooked through and toss with teriyaki sauce and sesame oil. Add broccoli back to pan and mix to combine. Enjoy.
