To roll the egg rolls: place egg roll wrapper on a diamond. Spread about 2 tablespoons of cheeseburger filling in a line, leaving about an inch on each side. Gently and carefully, fold the corner that's closest to you over the cheeseburger mixture, and tuck under the filling. Fold both side corners toward center of wrapper, it will start to look like an open envelope. Dip your fingers in egg white and run it along the edges of the wrapper to seal better. Carefully roll up the egg roll.
