EYEtalian dressing has it's place. One of the recipes I have for a BBQ shrimp type recipe has it as an ingredient and it's a darn good tasting dish that works well for a crowd. I don't use it much, but I usually keep it around.
The seasoning-I don't use much because I don't always want every ingredient in the mix in the dish I'm cooking. I grow fresh herbs, also, so I use those a lot. However, I ordered a dry Italian seasoning mix from a deli in WI a while back for Pioneer Woman's Italian Drip Roast and I really like this mixture. Haven't used it on anything else yet, but it's cheap and there's a lot of it. The salted version is really salty, but really good. I ordered the unsalted version and I mix them. LINK
