COOK and stir vegetables in dressing in large skillet 5 min. or until tender. Cool 10 min.; drain.

HEAT oven to 375°F. Unroll dough on baking sheet; firmly press perforations together to form 12x4-inch rectangle. Sprinkle with cheese; spoon vegetable mixture down one long side of dough. Roll up dough lengthwise, starting at vegetable-topped side; rearrange log, if necessary, so log is seam-side down on baking sheet.

BAKE 20 min. or until golden brown. Cool 5 min. before slicing to serve.
