I'm interested in more salad dressing recipes, too.
I make a green goddess dressing a lot.
Into the food processor I put about equal amounts yogurt and mayo. A good amount of salt and freshly ground black pepper. Granulated garlic (or fresh). A dash of ACV. Then a big bunch of either parsley or cilantro and a small bunch of chives. A dash of cayenne. Blend until creamy. Thin with milk if needed or leave thick as a dip.
