BARF - the prep is easy, no need to cook anything (it's not raw food if it's cooked).
For every meal my labx gets chicken carcasses or lamb bones and minced butchers scraps. Once or twice a week he gets a whole sardine, an egg (including shell) and fine chopped veg (all raw) and table scraps whenever there are any (not often in my house).
My dog looks great, he works great and his stools are small and solid. I wouldn't recommend anything else.
