<<Disclaimer: Verify this information before applying it to your situation.>> Hello.... I have not posted to this list previously, but have been on the list for a little while. I am a musician on the road, and yesterday, in Jackson, Michigan, ate at a Big Boy Restaurant. The manager was very accomodating, even bringing out the packages of salad dressings, cottage chesse, etc., for me to read to see what the ingredients were. Within a short time, he was aware of what I needed to know, and was checking items in the kitchen and coming out to tell me. The brand of cottage cheese was probably indigenous to this area, (Prarie Farms) but he said that all of the salad dressings came from the company headquarters, so all Big Boy's would be the same. (no wheat protein, or modified food starch). I checked out about 5 different flavors of salad dressing, including the Ranch & Blue-Cheese. ( so far FOR ME....I have not been affected by ingestion of any vinegars, but just one bite of ANYTHING like bread or gravy or ANYTHING like that will send me into very bad "episodes") The salad bar had enough items on it that I could eat, and even tho the cottage cheese was not on the salad bar, he brought me out a nice size bowl, since I could not partake of all the items. So, for me, and I hope for others this will help when travelling, or wanting to eat out. Regards, Judy Miller
