Italian Salad Dressing From Scratch

I’m trying to find a good Italian salad dressing recipe, since buying a bottle of dressing that’s made with olive oil instead of industrial seed oil (soybean oil, canola oil, etc) is virtually impossible.  This recipe was pretty good except that it was way too salty, even though I did cut the salt quantity in half.  And honestly, a dozen ingredients seems a little crazy for just dressing.  But it did make a neat pattern as I added ingredients to the jar.
