a few 'white beans' (e.g. cannelloni, haricot)
a bit of smoked salmon
lemon juice (from a bottle is fine)
titchy bit of light mayo - as little as you can get away with to get the texture
pepper and a bit of salt (maybe)
It also helps to have a mini chopper/blender
In the bowl put the beans, smoked salmon and some lemon juice. Zizz it up together. Add just a little bit of light mayo as it helps the texture. Zizz and taste, adding more lemon juice if you like and a bit of pepper and, possibly, salt. It depends on how salty the salmon is really.
If you have some fennel fronds or similar, that would be nice but I didn't.
Heap into a bowl and serve. I had it with watercress and a couple of small slices of bread I baked in a coolish oven until crisp and crunchy. It was delicious!
