its a suspension. more specifially a colloid. emulsion.

Salad dressing.
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.
Suspension
vinaigrette
Salad is considered a suspension because it consists of solid particles (such as lettuce, vegetables, and croutons) suspended in a liquid (such as dressing). In a suspension, the particles are large enough to be seen and do not dissolve in the liquid. Solutions, on the other hand, are homogeneous mixtures where the solute is completely dissolved in the solvent at a molecular level.

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.

If you can see particles (like spices) in it, it's not a solution.If it separates, it's not a solution.Italian dressing has both those properties, so it's not a solution twice over.
Salad dressing contains some kind of oil mixed with vinegar, and these two substances are immiscible; they do not dissolve in each other, although if you mix them together you can get a suspension (which is temporary).
