In a medium bowl, stir ingredients together until smooth.
Preheat grill or broiler.
Thread vegetables onto wooden or metal skewers. If you use wooden ones, soak them in water for 1 to 2 hours before using to keep them from burning. You can make single vegetable skewers or use an assortment on each skewer.
Lightly brush each skewer with marinade. Broil 4 to 6-inches from heat, 5 minutes per side or until browned or lightly charred and tender. If desired, serve with extra marinade for dipping.
