One loaf of white fresh bread (crustless)
400g canned tuna (I always use Rio mare)
350g whole egg mayonnaise (or make your own) or don't bother!
How to make:
1: Rinse the capers to remove any excess salt or vinegar. Mix through with the mayonnaise
2: Remove all the crusts from the bread
3: Layer the bread with the tuna, place a piece of bread on top, then layer with the caper and mayonnaise mix and top with another piece of bread (yes, it's a double decker)
4: Cut into small triangles, and serve
