Fact: I have not purchased salad dressing in over fifteen years. We have made our dressings from scratch for as long as I can remember. They're delicious, healthy and most are made with less than seven ingredients. Store bought dressings have ingredients in them that I don't want, including sugar, potassium sorbate, xanthum gum, and unhealthy vegetable oils like soybean and canola. Not only is making dressing from scratch EASY but it will save you money.
