"Schnitzel" is also very popular in the Czech Republic, where it is known as a "smažený řízek" or just "řízek", and is made of pork, chicken, or veal. It is often served with boiled or mashed potatoes or potato salad. It also used to be and to some degree still is a typical packed lunch for day trips, when it was consumed with bread (often between two slices of bread as a sandwich). During the communist period, a deep-fried breaded hard cheese called "smažený sýr" (literally, "fried cheese") became popular, mainly among the youth and students, especially served with tartar sauce, a slice of lemon, and boiled new potatoes with melted butter and parsley greens.
