Recipe Instructions
Step 1
Whisk soy sauce, vinegar, brown sugar, green onions, garlic, and mustard powder together in a bowl; pour into a resealable plastic bag. Add steak, coat with marinade, squeeze out excess air, and seal the bag. Marinate in the refrigerator, 3 to 4 hours.
Step 2
Remove steak from marinade; shake off excess. Discard remaining marinade.
Step 3
Heat a non-stick skillet over medium-high heat. Add steak; cook until outside is seared, about 1 minute per side. Continue cooking until desired doneness is reached, about 5 minutes more per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C) for medium.
Step 4
Transfer steak to a cutting board; rest before cutting, 3 to 5 minutes. Sprinkle sesame seeds over steak.
