I didn't get to try this until today. I didn't have pepperoni, so I got to try the freeze-dried sausage from Packit Gourmet that I recently bought. It worked great! I hydrated the sausage and onions separately from the potatoes, and I also added a little salt. Very tasty and satisfying.
I'm making a notebook of all the recipes I try and like, and I've categorized them by the main filler ingredient: potatoes, couscous, rice, and pasta. There's quite a good collection now, mostly from you and Sarah. Thanks for sharing all these and thanks for your great books and websites!
