To Prep
In a shallow dish, combine all marinade ingredients and add the beef slices. Mix well and let marinate for 1 hour.
Trim the roots of the enoki mushrooms, leaving just enough so the stems stay attached.
Separate into small bundles and soak in lukewarm salted water for a few minutes. Drain well.
On a clean surface, lay one slice of beef flat. Place two bundles of enoki on top, facing in opposite directions. Roll the beef tightly around the mushrooms.
Repeat with remaining beef slices.
To Cook
Heat cooking oil in a pan over medium-high heat.
Add the rolls and pan-fry, turning occasionally, until evenly browned and cooked through.
Transfer to a serving plate, then pour the remaining sauce from the pan over the rolls.
Garnish with sesame seeds and serve hot.
