My salads are walnuts coleslaw, bag of ready done salad, a tomato, some cucumber, radishes, beetroot (fresh not pickled) celery, sweet red or yellow pepper, some finely chopped onion,black pepper (freshly ground) some really good olive oil and red wine vinegar with a sprinkle or squeeze of lemon or lime juice. If from a real lemon/lime I usually cut some very thin slivers and chop them to tiny bits before throwing them on top.
I do have a zester somewhere - I must look it out so I can add in more lemony goodness.
