Canned sardines on toast with capers & red onion

From our fishy friends at Rockfish: sardines on sourdough toast with capers and red onion — simple, tasty, and ready in minutes!

Ingredients

1 x can sardines

sardine mayonnaise 

½ red onion, finely sliced

1 tablespoon capers, rinsed and drained

1 tablespoon finely chopped curly parsley

1 dill pickle, finely sliced

2 slices of sourdough bread

salt and white pepper

Method

To make the mayonnaise whisk together the egg yolk, dijon mustard and tomato paste. Drain the oil from the can of sardines and slowly drizzle it into the yolk mixture while whisking to build up a nice thick mayonnaise. Season and add a splash of Tabasco or other chilli sauce to taste.

Put the sardines in a bowl with the onion, capers, parsley and pickle. Gently break up the fish but leave nice chunks. Season. Toast the bread, then heap the sardine mixture on top. Serve the mayo on the side.
