Huzarensalade is a Dutch take on the Olivier salad. What belongs in this salad and what doesn't is a controversial issue, but it's usually prepared with a combination of potatoes, tart apples, gherkins, gherkin juice, carrots, shallots, ham or cooked veal or beef, mayonnaise, peas, and seasonings.
The vegetables are cooked and combined with the rest of the ingredients, and the salad is then typically chilled before it's garnished and served. It is named after the salad the Hussars (Hungarian cavalry) used to prepare. They usually went behind enemy lines and weren't noticed by the enemy, so they used pre-cooked food and mixed it on the spot in order to make this salad.
