Make marinade by combining the first eight ingredients in a bowl. Slice the beef into 48 very thin (about 1/8" thick) 3" to 4" long strips, adding them to the bowl as you go along. When done slicing, toss the beef with marinade, cover, refrigerate and marinate 4 hours, or overnight.
Divide and thread 2 slices of meat on the end of each skewer. Preheat barbecue or indoor grill to medium-high. Lightly oil the bars of the grill. Grill the skewers, 2 minutes per side, or until nicely charred.
Arrange on a platter and enjoy.
If desired, serve the skewers with Asian hot chili sauce, sweet chili sauce, spicy mustard or other Asian-style condiment for dipping.
Note: Mirin is a sweet mixture made from rice with wine available in the Asian foods aisle.
Recipe Options: Instead of beef, slice, marinate and use another type of meat on these skewers, such as lamb leg or sirloin, or pork tenderloin. For added texture, once cooked and set on the serving platter, sprinkle the skewers with a teaspoon or two of toasted sesame seeds.
