If you are looking for a dressing to purchase, my favorite is T.Marzetti's Light Caesar Vinaigrette. They are usually found in the produce section of the supermarket, although these are not the refrigerated ones in jars -- they are in regular salad dressing bottles. Anyway, I've tried several of the varieties in this line and love them all! Much better than any non-fat dressing on the market, but still not bad for you
Not really a Caesar dressing but my *favorite* Salad dressing is and will always be Girards Light Champange Dressing. Mmmm so tangy! And I believe that it's made by the T. Marzetti people, so obviously I have good taste if Suzanne likes their products.
Speaking of ceasar..... I love Ken's Steak House light ceasar dressing. I have found it to be the best light of its kind. you can find it in most grocery stores I think.
I love Paul Newman's Caesar dressing from McDonald's. I'm pretty sure you could buy it at the grocery store, but I usuallly get that dressing on the crispy chicken caesar salad from McDonald's...
