I know. Who would suspect wheat in frozen veggies. The wheat was in the actual ingredients, not as part of a process in a facility disclaimer. It was crazy. I figured I was safe since it was just frozen veggies. Luckily I happened to catch it beforehand. Learned my lesson about reading the labels on everything with that experience.
Another one that drove me crazy was packaged potato salad. I usually like to make my own, but we were going somewhere and I didn't have time to, so I picked up a package of Kroger brand potato salad and the label had wheat on it. Not sure why they had to put wheat in potato salad.
