I found myself at Joe's Parkway in Bozeman yesterday looking for cheese, they have a great selection by the way, and was pleasantly surprised to see they carry some gluten free products. Here's a list of a few things I spotted and this can be a great resource for the college students since it's just across the street from campus.
Gluten free pastas
Gluten free pizza dough mix
Gluten free bread mix
WOW cookies (The WOW brand is also carried at Bonanza in Billings)
The prices were comparable so if you haven't been in awhile, or ever, stop by. It's a nice local gem. I had to peel myself away from the spice and sauce area, too tempting.
I also wanted to note that Rosauer's Huckleberry Market now carries the Udi's bread and pizza crusts in the frozen section. Hubby and I tried their blueberry muffins and they were good, so good we both ate two instead of the planned one. Their webpage states that The Co-op carries their stuff along with Rosauer's in Missoula and Good Earth Market in Billings.
