I had a customer ask for some healthy salad dressing recipes, since she was allergic to soy (and many prepackaged dressings contain soy). In doing some research I came across this webpage, which has a full list of healthy, natural salad dressings which are easy to make and don't require exotic ingredients. I'm partial to the Sweet Asian dressing which I've reposted below, but she has several others on the site which sound delicious!
Sweet Asian Salad Dressing
1/3 cup olive oil
3 Tablespoons apple cider vinegar
2 teaspoons soy sauce
2 teaspoons honey
Pinch of dried ginger or 1/2 tsp fresh zested ginger root (preferable)
Spices to taste
