soak 16-12" wooden skewers in warm water for 30 mins. Thread steak onto skewers evenly. Place skewers in lg baking dish.
In medium bowl, stir together all remaining ingredients and pour over meat. Turn to coat. Cover and refrigerate for at least 4 hrs. ( the longer you let meat marinate, the better the flavors will meld.)
Spray broiler rack w/ cooking spray and preheat broiler. Drain marinade into small saucepan and bring to a boil. Boil, stirring constantly until sauce is thickened, about 5-8 mins. Place skewers on broiler rack, broil 5" from heat for 4 mins. Turn and broil another 4 mins. Watch to make sure it doesn't overcook, since oven temps vary. Place skewers on platter and drizzle the sauce evenly over meat. I sometimes serve the skewers over plain white rice.
