I know some people like to 'make their own', but I've never done that. I also don't like vinegarette, etc.
My old favorite, years ago, was Thousand Island. It's ok, but not my preferred now. A few years ago, my favorite was Kraft's Cucumber Dressing. Alas, you can no longer find that in my area. But I googled it: I can order it for $15 (2 bottles)--no, too expensive!
So, I ended up using a local market's version which is pretty similar: Cucumber Ranch. I love that one. However, the last couple of times I've gone shopping, they are out of that one. Next, I went to Wishbone Ranch, because the pictures showed a lot of 'veggies'; that's okay, but not great. It'll do in a pinch, though.
So this past shopping trip, I decided to try something different. I got Marzetti's Sweet Vidalia--very good! and I also tried Brianna's Poppyseed dressing--not bad, but a bit more tart than I prefer. So at least I have some choices, if I can't find the ones I prefer!
