Creamed Chipped Beef On Toast - I grew up with my mom making this. I don't use the cayenne pepper and I used packaged beef instead of dry. It is good, simple and fast. Mother made ours over biscuits too.
AMISH/ Mennonite Dried Beef Gravy I grew up on this served over toast, but it's great over biscuits or mashed potatoes. Added a tad bit more flour to thicken and used half can of dried beef. Rinsed beef under warm water first.
