Combine the tuna, celery, and mayonnaise. Place one slice of Swiss cheese
on each of two slices of bread. Spread half of the tuna mixture on top of
each and top with remaining bread slices. Dip each sandwich into beaten egg
and then into the potato chips.
Melt 2 tbsp. butter in a skillet or on a
griddle. Brown sandwiches on one side and then on the other until the
cheese is melted. Serve with carrot sticks and milk.
