I have many relatives and friends who must avoid gluten, and it's in almost every dressing. It's especially difficult in restaurants, as most gluten free menus focus on salads, but the only available gluten-free dressing is oil-and-vinegar. A line of gluten-free dressings for home use, and a line that restaurants could put on their menus so even the staff would be able to tell the gluten content, would be perfect.
