Place vegetable skewers on grill (near edge of coals but still over coals if using charcoal or on cooler side of grill if using gas).

Continue to cook vegetable skewers until tender and lightly charred, about 5 minutes; transfer to platter. Using tongs, slide beef and vegetables off skewers onto platter. Serve.
