Separate egg yolk from egg white. Set egg white aside to be used later to seal the wrapper.

Brown ground beef in a large skillet. Drain in colander; rinse well with hot water to remove as much of the fat as possible. Return ground beef to pan; add onion, carrot and celery. Cook over medium heat for 2 to 3 minutes. Season to taste with salt and pepper. Cool slightly. Add egg yolk and mix well. Drain in colander.

Take one lumpia wrapper and place a line of ingredients ½-inch wide approximately 1-inch from edge. Roll firmly as for an egg roll, bringing sides toward center to cover the edges. Seal the edges with egg white.

Cook in medium hot oil, turning occasionally until browned on all sides. Drain on paper towels.

NOTE : What you don't cook can be frozen for later use. When cooking lumpia that has been frozen, do not let it thaw out before it is fried.
