You'll need:

1 tin of sardines. I used Waitrose in olive oil
Green leaves, bowlful
Large handful of small plum tomatoes, halved. I used Datterini
Quarter of a red pepper, cut into small chunks
Slice of lemon

Method:

Put the washed leaves into a bowl. Tip on the tomatoes and red peppers. Drain and discard some of the oil from the sardines. Place the sardines on the salad, then pour over any remaining olive oil. A grind of black pepper plus a slice of lemon, and you're done.

Effort to taste ratio (both out of 10):
1:8

Verdict:
I'd forgotten about sardines, 'til I saw a tin in the supermarket. Fishy loveliness. Those omega 3s definitely made me write better.

They’re great with rhubarb too.
