This is a great substitute for commercially-made ranch dressings. It has no additives or preservatives. If you have allergens to dairy try a buttermilk made from raw milk. It’s really good for you.
1 cup buttermilk
1/2 c olive oil
1 T Italian seasoning
1 t salt or more to taste
1/4 t pepper
Mix thoroughly and then mix again if ingredients become settled before putting on your salad. Enjoy!
