My 15 year son is starting to workout. I want him to only get his nutrients from real foods and maybe a shake once in a while. Problem is that he is a real finicky eater especially in the morning. He hates eggs so what are so alternatives for him to get his protein. Any godd natural food shakes that can be made that taste good, I think this may be the easiest thing for him. And by the way we are trying to bulk him up. Thanks.
