For lunch I do something light like sandwiches, pasta or jacket potato with cheese, ham, chicken etc

I always put cucumber, tomato, carrot sticks or slices of pepper with whatever I do, a combination of 2 a day. Surely there must be some alternatives I could provide? I just can't think of any. I've tried lettuce, but no one eats it and anyway, I don't ever think there's much substance to it.

Has anyone got any other suggestions?
