In the mid 1970’s, I worked as a long distance telephone operator in Seattle and worked out of the 4th Avenue office. Across the street was The Hungerford Hotel and they had a lounge that was one of the first places to get the Pong computer game. We would go over there for lunch, play pong and have a beer (or two) and grilled tuna and cheese sandwiches and then go back to try to work.
Grilled Tuna and Cheese Sandwiches
Mix a can of drained tuna fish with chopped celery, onion and dill pickles and mayo to taste. Spread slices of bread (any kind) with tuna fish and then top with cheese slices (any kind).
Grill in oven until one side is toasted and then turn until other side is toasted and cheese is melted.
Option: butter both sides of sandwich and pan-grill until both sides is toasted and cheese is melted.
Option: use mayo instead of butter on both sides to grill the sandwich.
