I've used egg white powder, eggs, pork panko. I prefer doing small "buns" or tortillas instead of a full loaf. A bun is 1/4 c pork panko, 1 egg, 1 T butter, baked for 10 mins @ 400F. My pork panko is pork rinds in the food processor. If you need a different type of recipe find Courtney Luna. She has lots of ideas/recipes. 🙂
