We love whole foods (I don't love the prices!) but there are a few things we buy there a lot. First, if you want to make pies (fruit, quiche, chicken pot pie) we love their brand of frozen pie crust. The best! I take it to Holidays for get togethers, and no one knows its gluten-free. There are 2 in a package in the freezer.
We also love the Against the Grain Baggets (spelling?). There are 2 long thin loafs in one bag in the freezer section. SO good. We use them to make french dips, subs, and most often garlic bread. So good! I also stock up on the gluten free "graham" crackers. They are nice to have when the kids aren't feeling good. Easy on the tummy. Good luck!
