This is an awesome recipe for faux sour cream using greek yogurt and lemon juice. It tastes exactly like sour cream with a fraction of the fat and calories. It's from Bethenny Frankel - celebrity natural foods chef, author, and star of Bethenny Getting Married and The Real Housewives of New York City. I read about this recipe in her book, Skinnygirl Dish. I've put this on top of huevos rancheros, fajitas, tacos, baked potatoes, and chili. Try it, you will not be disappointed.
