If mozzarella balls are larger than 1/2-inch in diameter, cut into cubes to size. Wash and dry tomatoes and basil. If basil leaves are large, these may be cut in half.
Using small skewers about 4 1/2 inches long, slide on a tomato, a piece of basil folded in half and a cube of mozzarella. Repeat on new skewers until all the pieces have been used.
Combine ingredients for dressing and brush or sprinkle over skewers just before serving. Dressing can also be served on the side for dipping.
