100g mayonnaise (an olive oil one works best)
1 tbsp capers, drained
from a can, 1 cut into thin slices
80g tuna in oil (a good-quality one will make all the difference here), drained
juice ½ lemon
400g/14oz or thereabouts leftover turkey- white and/or brown meat
100g bag rocket
Put the mayo, most of the capers, 1 whole anchovy, the tuna and most of the lemon juice into a food processor. Whizz until the tuna is completely mixed into the mayo.
Season with pepper first, then taste, and add salt and more lemon juice, if you need to. If your sauce seems a bit thick, whizz in a drop of water. Can be made up to a day ahead.
Spread the turkey and rocket over a large serving plate, then spoon over the dressing and scatter with the remaining capers and sliced anchovy. Serve straight away.
