It is just a mixture. However, the salad dressing may be a suspension. For instance, Italian dressing is made using oil and vinegar which of course does not mix well.
Short answer: No. A salad dressing is specifically a colloid emulsion (when shaken/prepared), but easily becomes a suspension as the oil and water (in the vinegar) separate over time. On top of that, things like mustard seeds and herbs cause the dressing to become a mixture (as they could be filtered out). A salad in its entirety is a mixture, as the leaves are not dissolved in the dressing. So, salad cannot be a solution and neither is its dressing.
