Step 1

Mix all the salad ingredients together and season with salt and pepper.

Step 2

Spread a quarter of the salad mixture on the bottom half of each focaccia. Layer the meat and cheese on top. Use the remaining salad to cover the cheese and put the top half of the focaccia on.

Step 3

Wrap both sandwiches tightly in cling flim, greaseproof paper or a snug plastic box and allow to rest for at least an hour in the fridge. Ideally, allow the sandwiches to come back to room temperature for 15 minutes before eating.
