Do you have a favorite dressing you always go back to for salad?

I still like ranch but unless I make it, I don't like the bottled stuff.
I don't make it often cause salads around here aren't made often enough to use it up.

I buy jarred blue cheese from the fridge section at the store, its good....I've tried their ranch, not so good.
Maybe I see if there is another brand to try.
