1 tin Sardines.
Sliced red onion.
Wedge of Lemon.
Bread or good quality crackers.
The first thing to do is go on to ebay and buy yourself a good sardine fork. After you win your auction, use the sardine fork to plate each sardine on a slice of bread or a cracker. Pick and choose your accompaniments, topping one bite with a bit of onion, the next with a squeeze of lemon, and the third with mustard.
