Olivier Salad is a popular dish in many Eastern European countries, particularly in Russia. It is a hearty salad made primarily from diced boiled vegetables, such as potatoes, carrots, and peas, combined with diced pickles and sometimes boiled eggs. The salad is typically dressed with mayonnaise, giving it a creamy texture. Originally created in the 1860s by the Belgian chef Lucien Olivier, the salad has evolved over time, with various regional adaptations. Some versions include ingredients like chicken, ham, or fish, making it a versatile dish often served during celebrations and holidays.
