TD, brown some breakfast sausage, after its browned add flour to the amount of grease in the pan, stir it, let it cook for a few minutes to absorb the grease then add some milk. Let it thicken and then add just a bit of water to thin it a bit, add some black pepper and some hot pepper flakes if you want it a bit spicy. Let it cook a few minutes and it's ready to eat. I usually put the biscuits in the oven before I start the gravy. By the time the biscuits are done, the gravy is too.
