Tbh at the moment it's tuna n salad lol.
Then you might like this.
Start with a large glass bowl.
Finely chop 1/2 cup of onion
Finely chop 1/2 cup of celery
Add 1 tbsp soy sauce
Add 2 tbsp sweet relish
Add 1 tsp celery salt
Add small amount of ground white pepper corns
Drain 4 tins of Tuna really well, get out as much liquid as possible
Mix it all a together in the bowl extremely well
Add about 90% of a cup of full fat Hellmans Mayo and add a little extra if it seems too dry.
Avoid making it too wet because its a pain to reverse that.
Mix well and put cling film over the bowl and leave it in the fridge overnight.
Next day you can add more mayo if its too dry.
Lightly toast high quality bread and butter well, some people melt cheese to make it a tuna cheese melt or add salad like lettuce and tomato. Or just have the tuna mix on its own.
This is close to how New York Deli`s make it, or so says a guy who used to work in those places.
