This recipe serves 4 hungry theme park guests:
Mix one can of Chicken of the Sea Tuna with 1 tablespoon of chopped onion, a quarter cup of chopped celery, a teaspoon of lemon juice, and two tablespoons of mayonnaise. Slice 4 hamburger buns (the kind with sesame seeds) into 3 horizontal sections. Spread tuna mixture onto the middle bun slice.
Now mix 2 more tablespoons of mayonnaise with 2 tablespoons of catsup (it'll make kind of a 1950s version of pink "thousand island" dressing); spread that onto the bottom bun slice and cover with a layer of sweet pickle slices. Put all the sections together to make a a "triple decker" sandwich.
Wrap it up in aluminum foil (Kaiser of course!) and bake in the oven (at 375) for 15 minutes. Eat it hot! Yum!
Serving suggestion: Turn this into a real vintage Disneylander's lunch with Fritos and a Pepsi!
