I came up with the recipe after finding other caramel apple salads on here. I loved the idea, but I don't like cool whip or instant pudding so I substituted greek yogurt and dulce de leche, which you can make out of a can of sweetened condensed milk. Both of the stovetop method and the slow cooker method have worked for me. Here is the slow cooker recipe that I used: http://www.food.com/recipe/crock-pot-dulce-de-leche-420669. This recipe does provide a whole serving of yogurt and fruit.
