Beat salt and egg whites with electric mixer until stiff peaks form. Set aside. Put all the remaining ingredients in a blender and blend until smooth and creamy. Pour the cheese mixture into the egg whites. Gently, but thoroughly, fold together. Spoon the mixture into a 9" nonstick square or round cake pan. Bake in a preheated 350 oven for 40-50 minutes, until a knife inserted in the center comes out clean. Chill thoroughly. The cake sinks in the center as it cools, making a depressing for fruit. Fill with berries or sliced unsweetened peaches to serve. Per serving: Calories--69.1 Carbohydrate--2.0 grams Fat--2.3 grams SOURCE: Calorie-Carbo-Fat Counter & Cookbook ----
