Hard-boil one egg per person and remove the shell.
Cook some french beans for about 3 mins in boiling water. Drain.
For the tomato and bean salad: I like to make this salad on a plate, just because it looks pretty. Slice a few large tomatoes and arrange on a plate with the cooked green beans. You could add some capers or black olives if you have some. Pour over the dressing. Leave to marinade while you cook the tuna.
