PREHEAT oven to 400°F. Cook ground beef, bacon and onions in large skillet on medium-high heat until ground beef is evenly browned, stirring occasionally. Drain; return meat mixture to skillet. Add Cheez Whiz; cook until completely melted, stirring frequently. Cool 10 min.

UNROLL dough onto baking sheet sprayed with cooking spray. Press into 14x7-inch rectangle, firmly pressing seams and perforations together to seal. Top evenly with meat mixture. Roll up dough, starting at one of the long sides. Rearrange, if necessary, so roll is seam-side down on baking sheet.

BAKE 20 to 25 min. or until golden brown. Cut diagonally into six slices to serve.
