In a shallow dish, mix together the soy sauce, oil, garlic, ginger, and
some pepper. Add the beef and marinate overnight in the refrigerator, turning
once.
Heat the broiler. Pat the marinated meat dry and broil the steak, about
4 inches from the heat, until rare, 5 to 6 minutes per side. Cool completely
and then slice very think on the bias, across the grain of the meat. Trim
the slices to form approximately 2" x 4" strips.
Brush a thin layer of hoisin sauce on each strip of beef. Lay a small bundle
of scallion julienne at one end and roll up securely. Arrange on trays, seam
side down, cover tightly with plastic wrap (make sure the plastic is in close
contact with the beef), and refrigerate until time to serve.
