What would be OK for me to eat at Passover?

For one week you can go and buy Matzoh, unleavened bread. It is just plain flour and water with no additives so it won't complicate any dietary problems you have. It really is that simple, for the week of Passover, use matzoh instead of bread. if you don't know where to buy it, just ask anyone coming to there, they will all know.
