Use a fork to flatten salmon in a dish and crush bones and all. I always take out the bigger bones.  Add egg.  Stir.  Add chopped onion and Italian bread crumbs.  Mix well.  Might need more bread crumbs than I listed. Needs enough to form patties that will hold their shape to fry.  Fry in a skillet with a little oil or butter flavor Crisco until browned. Really Good! My mom always used crushed cracker crumbs rather than bread crumbs. I like them both ways.
