Tuna, Potato and Bean Salad

I had intended to make that brilliant French staple Salad Nicoise today, but a lack of the right in ingredients (lettuce, the right vinegar and most damningly any eggs) in my cupboard, means that I have to make a poor cousin: Tuna, Potato and Bean Salad.
It may not be the same, but it is still fairly tasty as I stir basil pesto mixed with olive oil into cooked new potatoes and runner beans, before seasoning and scattering over halved cherry tomatoes and flaked tuna. I really like it apart from the tomatoes. I still hate the texture of those red ones.
