Place steak pieces in a gallon size resealable bag.
In a mixing bowl whisk together soy sauce, honey and garlic. Pour over steak, seal bag while pressing out excess air then rub marinade over steak.
Transfer to refrigerator and let marinate 1 - 2 hours.
Heat 1 Tbsp oil in a heavy non-stick skillet over medium-high heat.
Remove half the steak from marinade, transfer to skillet (spaced apart) and let sear until golden brown, about 1 minute then flip to opposite side.
Let continue to cook to desired doneness, about 1 minute longer (internal safe temperature is 145 degrees). Transfer to a plate and repeat with remaining steak.
Serve warm garnished with green onions or sesame seeds if desired.
