While the English Earl of Sandwich is generally credited for inventing the snack of his namesake, Hillel may have originated it two thousand years ago by combining matzah, a slice of paschal lamb, and a bitter herb, often referred to as a “Hillel Sandwich.” Jews no longer sacrifice and eat a lamb, so now the Passover sandwich is only matzah, charoset, and a bitter herb. Most people just make it and eat it, although some people say these words first:
“This is what Hillel did, at the time that the Temple stood. He wrapped up some Pesach lamb, some matzah and some bitter herbs and ate them together.”
