Cut your steak into 1.5 inch cubes, try to keep them uniformed in size to make sure they're cooked evenly. In a large plastic storage bag marinate your beef with all the ingredients preferably overnight or at least two hours. Soak the wooden skewers in water for about 20-30 minutes {to avoid them burning up when they're on the grill}. Assemble your skewers alternating veggie and steak. I cut my cubes up fairly large and was able to fit 3 pieces of meat per skewer.
