What did the people eat in the Warsaw Ghetto?

They ate soup and bread usually, but in the mornings they has bread and coffee. but yes, they were starved. The ss locked the prisoners in a barrack without anything to eat or drink and left them there for days. After a long while, they would place soup or bread just outside the door of the barrack, open the door, and amuse themselves, watching the poor innocent people trample over each other to get to the food.
