Flank Steak Roll Ups

In a blender, combine marinade ingredients and blend until smooth. Using a sharp knife, slice the steaks at a 45-degree angle into thin strips. Submerge the steak in the marinade, cover, and refrigerate for at least 2 hours, or overnight.

Preheat a grill to 350°F and use a paper towel soaked in olive oil and a pair of long-handled tongs to oil the grate. When ready to assemble, lay the steak strips flat on a cutting board. Arrange two pieces of each sliced vegetable on each piece of steak. Roll up each steak piece and skewer so the meat is tightly wrapped around the vegetables. Grill the steak rollups, rotating as needed until cooked evenly. Meanwhile, in a bowl, combine the chile oil, soy sauce, and scallions. Drizzle the sauce over the skewers, or serve on the side.
