Oh Alpha, that Mom is a moron! Sounds like she is definitely a micromanager but doesn't she have common courtesy? It is true that you can't please all of the people all of the time, but that was just rude! I hope you let the comments roll off your back and you have forgotten about it by now. Don't lose any sleep over an ignorant comment.
I think your menu sounds nutritious and well balanced. All of my food is home cooked and I only have one Mom who asks me to email her daily to tell me what I feed her very picky daughter so she can give her different things in the evening and the rest don't care at all about my menu so I stopped making one years ago.
I also serve mostly organically grown fruits & veggies but I draw the line there because the cost of so many other things like meat are very expensive. But I know for a fact I'm serving all the daily nutrition that a few of the children in my care will eat because prepackaged food is served at home.
