First thinly slice your beef and make the beef marinade. Blend the marinade in a blender to mix it and marinate your meat with half of it. Marinate your beef from 3 to 24 hours. I usually marinate about 6 hours.
The other half or your marinade goes in a pan and cook it slowly to reduce it by half.
For the slaw shred all ingredients and put in a bowl. Set aside.
For the dressing mix all the ingredients together whisking in the olive oil last and set it aside
Heat your skillet to high and cook your marinated meat 2 to 3 minutes on each side.
Heat your flat breads. I heat these quickly in a cast iron skillet, cooking on one side until heated through.
To assemble place a handful of the slaw in the middle of your flat bread, top with meat and drizzle with both the dressing and a some of the reduced marinade.
