UNROLL pizza crust; cut into 6 squares. Place on baking sheet sprayed with cooking spray.
TOP each square with 3 pepperoni slices, 1 Tbsp. sauce and about 3 Tbsp. VELVEETA. Gather 4 corners of each square at top to partially enclose filling; pinch edges of dough together to secure.
BAKE 10 to 12 min. or until crusts are lightly browned.
MICROWAVE remaining pizza sauce in microwaveable bowl on HIGH 30 sec. or just until warmed; stir. Serve with pizza pouches.
