How would you make this breakfast casserole?

I'm trying to make a casserole with what I have, but I have never even made a breakfast casserole.

I have eggs, cheese, ground sausage, bacon, crescent roll sheets, and potatoes. The potatoes, I may want to put in the casserole, or maybe just make them as a side. I do want the crescent roll dough in the casserole though.

Any tips?
