Hamburger Roll-up

1 lb. lean ground beef
1/2 cup chopped onions (about 1 small)
1/2 lb. (8 oz.) Velveeta cheese.

1 pkg. (13.8 oz.) refrigerated pizza crust

1. Preheat oven to 350.
2. Cook ground beef and onions in large skillet on medium-high heat until ground beef is evenly browned, stirring occasionally. Drain; return meat mixture to skillet.
3. Add Velveeta in thin small chunks; cook until completely melted, stirring frequently. Cool 10 min. (It will turn almost into a paste consistency).
4. 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.
5. BAKE 20 to 25 min. or until golden brown. Cut diagonally into six slices to serve.
