Udi's gluten free bread is in our grocery stores. Check online also. It is a good sandwich bread. I prefer Sammi's millet bread that I get from the Health Food Store. Every now and then I use a Bob's Red Mill gf bread ix and have warm fresh bread. I do not like the shelf stable breads like rice and tapioca bread found in a lot of stores. I do not think it is hard to find but it is pricey. Well all gluten free specialty foods are pricey but you gotta eat.
