The search here is abysmal so I can't find if sausage was mentioned in here already. But I'm going to try this to reproduce a sausage cheese bread that a local bakery here sells. They add solid bits of scrambled eggs to theirs, but I think our way of using an egg mixed in with the batter and cooked that way would still be fine. So a sausage, egg, and cheese bowl muffin for breakfast. Yum!

I have just now found this post but I had already been using a bowl instead of a cup for all the "in a mug" recipes I was trying. So this is right up my alley.
