Parsley or another green vegetable.[1] Some substitute parsley to slice of green onion (representing the bitterness of slavery in Egypt) or potato (representing the bitterness of the ghetto in Germany and in other European countries), both commonly used. The dipping of a simple vegetable into salt water and the resulting dripping of water off of said vegetables visually represents tears and is a symbolic reminder of the pain felt by the Hebrew slaves in Egypt. Usually, in a Shabbat or holiday meal, the first thing to be eaten after the kiddush over wine is bread.
