If using wooden skewers, soak skewers in water.
Combine chili sauce, TABASCO® Chipotle Sauce, rosemary and salt in medium bowl. Divide mixture into 2 bowls. In one bowl, add beef chunks; toss to coat. Let stand 15 minutes.
Thread beef onto two 12-inch-long skewers. Alternately thread zucchini, yellow squash and mushrooms on remaining two skewers. Brush vegetable kebabs with reserved chipotle mixture. Grill kebabs 6 to 8 minutes or until meat is of desired doneness and vegetables are tender, turning occasionally.
Remove kebabs to platter. Garnish with rosemary sprigs, if desired.
