Gluten free, dairy free healthy lunch - 3 bean tuna salad

Today I had the healthiest lunch in the world. Well, ok, perhaps not in the world EVER, but certainly compared to my recent crap eating, it's pretty healthy:

It is a tuna and bean salad: kidney beans, chickpeas, white beans, a red pepper, spring onions and tuna, with a balsamic vinegar, mustard, thyme-and-oregano and olive oil dressing.

It is lovely.

Which is good, because there is so much of it, I may be eating it for the rest of my life...
