Bacon Cheeseburger Roll Up

1 lb. lean ground beef
4 slices bacon, chopped
1/2 cup chopped onions (about 1 small)
1/2 lb. (8 oz.) VELVEETA Pasteurized Prepared Cheese Product, cut into 1/2-inch cubes
1 pkg. (13.8 oz.) refrigerated pizza crust

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

UNROLL pizza dough onto baking sheet sprayed with cooking spray. Press into 15x8-inch rectangle. 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 6 slices to serve.
