Yep youngest basically just wants steak and/or chicken for every meal. He'll happily eat eggs and doesn't mind mince but refuses sausages.
I don't think he'd go full carnivore as there's stuff like chilli con carne and his favourite instant noodles (that he will load up with meat and eggs) that might be hard to give up as it will still be in the house due to the other two kids and I eating it.
