Salisbury Steak

1 egg, slightly beaten
1 lb. ground beef
Salt & pepper to taste
1/2 cup flour
1 sm. can mushroom slices (I omit this)
1-2 jars beef gravy

Mix together in order shown above (except gravy). Form into patties. In a
skillet, brown over medium heat on both sides. Reduce heat to mediumlow,
turning over with a spatula until crunchy-crisp on outside, and meat is
done on inside. Heat gravy separately; serve over meat.
