This is an asparagus and beef roll, seasoned with teriyaki sauce, and grilled. An extremely simple dish to prepare which makes an elegant presentation as an appetizer; it also works well as the main dish served over steaming white rice.
Preheat a grill pan until hot. Also bring a pot of salted water to a boil.
Blanch the asparagus spears in the salted water for about a minute. Drain and plunge the asparagus into an ice water bath to stop the cooking.
In a small saucepan, combine soy sauce, sugar, mirin, ginger, and garlic. Heat over medium heat until reduced and slightly thickened. Set aside and let cool.
Cut the green onions, lengthwise, into fourths, so that you have long strips.
Slice the beef into 1/4-inch slices. Gently pound them to both tenderize and thin out. Dip the slices into the soy sauce mixture and place on a clean work surface. Season with black pepper.
Place an asparagus spear and a piece of green onion on a beef slice and roll up. Do the same with the remaining asparagus and beef.
Grill the beef rolls about 2 minutes until slightly charred and medium rare. Turn several times and brush with soy sauce mixture. Remove to a serving platter and drizzle generously with the soy sauce mixture.
