Mix all ingredients for marinade and pour in a storage bag with steak to marinade. Let sit in the marinade for at least four hours under refrigeration.  As with all marinade, the longer the better up to 48 hours.

Preheat grill to 400F.

Skewer one piece of steak, a pickle, a shrimp, and a tomato, then repeat. I had enough for 4 skewers. 

Spray each side of the skewer with cooking spray. Place on the grill until steak is cooked medium well (or however you like it.)  Make sure to check the temperature should get to 145 F degrees minimum.  Turn them once halfway through, I turned mine about 3 minutes after they were on the grill.  They cook fast!
