Combine brown sugar, garlic, pepper, thyme and salt, mixing well. Combine 1 tsp of spice mixture with Italian dressing; reserve. Rub remaining spice mixture evenly over surface of roast.
Place roast on grid over medium ash-covered coals. Grill 25 to 30 minutes, turning frequently.
Meanwhile thread vegetables on each of 6 (12-inch) skewers. Brush vegetables with dressing mixture. Place vegetables on grid; grill 20 to 25 minutes or until vegetables are tender, turning occasionally.
Remove roast and vegetables from grill; tent with foil and let roast stand 10 minutes for easier carving. Carve roast across the grain into thin slices; serve with grilled vegetables.
