Mixed salad. Generally speaking a mixed salad indicates that it is not a green salad. A mixed salad may have the same mixture of green leaves that populate a green salad, but might have a couple of tomatoes or some radishes, some red leaves or some peppers to jazz it up. Naturally, the quality of the mixed salad, and the green salad, will depend on where you are eating it. It only ever appears as a side dish.
