Sounds delicious
My wife likes to substitute oatmeal for bread crumbs, and I must admit that it gives it a nice texture. I also like the idea of using ground beef, pork, and turkey - in my opinion the blend is texturally superior than using only beef.
I love my mother dearly, but her meatloaf was a bit mushy in the texture department, and I'd never tell her, but I prefer my wife's recipe
