Tuna salad lunch

On a normal Sunday I would have a large lunch, ideally followed by a sleep for an hour or so, then a lightish supper. This Sunday we reversed it. I couldn't sleep at all on Saturday night and gave up trying at about 6 o'clock - but then slept heavily for four hours from about 10 in the morning, just the time when I was going to make a casserole. So we had a tuna salad for lunch. I can't be bothered to say much about it as it's quite a regular meal for us so I'm sure I've blogged about it before. But here some of it is, in a bowl. I would have added olives (and more lettuce) if we had some, but we didn't.
