Mimoza is a traditional salad. It's prepared by layering different ingredients, and each one is separated by a light layer of mayonnaise. The ingredients include canned and mashed fish such as tuna, mackerel, salmon, or trout, boiled egg whites and yolks, onions, crumbled cheese, and sometimes boiled potatoes and carrots.

Almost all of the ingredients used in the salad are finely grated. The boiled egg yolks are usually the final layer, hence the name of the salad, because it looks similar to the spring flowers. The salad is often garnished with chopped dill before serving.
