My favorite is probably from Gordon Food Service, but I do not need a 2 gallon tub of it! I've bought some other ones from around here (Chicago), but I've never finished a bottle. Never found anything good. Heck, I prefer Wishbone Itlian to these other ones disguised as sub dressings.
What do you use or make? I don't have a huge selection of spices or oils but any good, tangy recipes would be appreciated.
