CheapHealthyGood has put together a great list of menu planners, price books and grocery lists. I found it because they linked to my old Excel pricebook, which you can download by clicking that link. It’s quite old at this point but may still be useful.
Lots of good looking stuff over there in addition to the excellent list in that one post.
Hope you enjoy!

I have a free downloadable menu planner here.
