Seems like a silly question, but wouldn't it be a better idea to not add a dressing to the salad? Personally, I'm not fond of anything on my veggies.

Also with salads be sure to stay away from iceburg lettuce specifically. Though using baby spinach instead of any lettuce is the best idea from what I've been told.
