Cheeseburger Roll-Ups

In a large bowl, combine beef, bread crumbs, onion, eggs, salt and pepper; mix well.
Pat out into an 18-inch by 14-inch rectangle on a piece of wax paper.
Spread cheese over meat, leaving a 3/4-inch border around edges.
Roll up jelly-roll fashion starting at short edge.
Press ends to seal.
Place on a lightly greased 15"x10" jelly-roll pan.
Bake at 350 degrees for one hour, or until internal temperature on a meat thermometer reaches 160 degrees.
Let stand at least 10 minutes before slicing.
Slice and serve on buns; garnish as desired.
