Welcome!
I think that is an excellent question and even something I've wanted for myself as a competitive bodybuilder. It is one of the more common questions I get, but I am not an expert at preparing balanced meals for general health. Perhaps I will be when I complete my current course in Plant-Based Nutrition through eCornell.
There clearly seems to be an interest in this and a void in where someone could come in with this service and help a lot of people. Perhaps there are forum members who do specialize in this. I can think of a couple off the top of my head and I'll send them over to this page and see if it matches what they do.
Thanks for being here!
All the best. PS, I'm from Corvallis and lived in Portland for a while

Now I'm a vegan cowboy of sorts, living in Texas.
