Susan Jung's recipe takes sardines on toast to the next level
Cure your own sardines or other oily fish, pickle some onion, toast some bread and there you have it

I love oily fish such as sardines, mackerel, anchovies and herring. One of my favourite quick lunches is sardines on toast, which is exactly as you would imagine: open a can of sardines (I like French, Spanish and Japanese brands), put the fish on well-buttered, good-quality toast, then pour the juices from the can over the top before eating. It's messy, but so delicious. Here are two recipes that take a little time to prepare (because you need to fillet the fish) but are a bit more elegant.
If you can't find fresh sardines, buy other varieties of small (10cm-12cm long), oily fish such as mackerel. Buy the fish the same day you're going to fillet them, and keep them on ice or in the fridge until you're ready to use them. Filleting small fish is much easier to do than it is to describe; once you get the hang of it, each one will take less than 30 seconds.
