I give mine chicken bones to pick the last bits off of. Recently I gave them the bones from some lamb loin chops (after eating them I remembered why I stopped buying them...the size and shape makes it too hard for me to chew that good meat off) they were very happy to clean those bones. And a couple days ago I gave them some tuna. They were on it like white on rice. Overall, they just get fruit/veg scraps from the kitchen with the rare "special" treat.
For daily treats, they'll get a mix of scratch with pellets. (about 7# scratch to 40# pellet)
