Methods/steps

Cut the flank steak in half along the grain and then slice it in thin 1/8 to 3/16 inch thick sliced across the grain.  Take the rest of the ingredients and mix them up.  I find it best to marinate the meat on a baking sheet with raised sides but if you don't have one the put everything into a large freezer and mix it up well.  You want to marinate everything for about an hour and turn it half way through to make sure that it all gets covered.

After about an hour remove the meat and put a few pieces onto each skewer.  I then put them on a plate lined with a paper towel to help dry off the meat.  It will brown faster this way.
Toss them all on a hot grill and leave the lid up while cooking.  They only need about 1/2 to 2 minutes per side.  Flip (I use tongs) and then cook the other side.
