ZionGate, my father says the same thing. To him sandwiches are only for making a meal portable. He doesn’t get the whole idea of eating sandwiches when you’re at home and can eat the bread and other things separately.
cmberzon, ZionGate had it right. The “stupid Bavlim” did not eat two pieces of bread together! That really would be stupid. They ate bread dipped in Kutach, which is a fermented sauce made mostly from yoghurt, stale bread, and salt . (Think of soy sauce, which is mostly soy beans, wheat, and salt.) This of course makes perfect sense, but in EY they made fun of it.
