French toast is an excellent way to use up some old stale bread; in fact, it works better if your bread is a little dry and chewy. The dryness of the bread absorbs the milk and egg mixture without falling apart and getting too soggy. Using a whole grain bread is another way to help your French toast keep its shape. The fiber and protein in the whole grain bread will prevent the liquid from dissolving your slice, whereas white bread will dissolve and quickly get mushy. Try a little experiment at home and compare a slice of white bread against whole grain when making French toast. This is a good visual to show how whole grain bread sits in your stomach longer, keeping you fuller and feeling satisfied longer.
