If your bread molds too fast...

If you have a problem with not being able to get through a loaf of bread before it goes moldy, consider rice cakes. I found some at a local discount grocer, for a really good price; I bought a lot. Now I wish I'd bought more. They last in the pantry for a long time, because unlike bread they do not have moisture. They make a great lower-calorie sandwich type food, with spread or toppings served open-faced; and they come in a variety of fun flavors, too.
