I think you're right Ruth. I always thought crumbs were needed for binder, but recently I've done meatloaves and meatballs with no crumbs or oatmeal, and they held together just fine. My family isn't crazy for straight turkey loaf though, so I usually mix it with some lean ground beef.
Life's a journey, not a destination.
It's easier to stay on plan than to get back on plan.
