I haven't done one in forever, but I was quite proud of my breakfast sandwich. The original used a hoagie roll and the final build used a brioche bun.
From the bottom up, it's bun bottom, mayonnaise, 1 hash brown pattie (1.5 for the hoagie), a slice of pepper jack cheese (1.5 for the hoagie), a fried egg shaped like the bun, another/1.5 slice of pepper jack, sausage (or 1.5), mayo, top bun.
I used to be able to put back two of the hoagies. I'd make two of them, put them on a plate, and go into my room and eat them. Now I can't finish one of the brioche ones.
