This recipe is an adaptation (since I can rarely leave a recipe alone) of a recipe from a Weight Watchers Magazine cookbook called "Two's Company". The only thing that would have made it better is some lovely Parmesan, but I forgot to buy it at the store. Grrr.
The original recipe calls for cheese ravioli, but I've used a variety of filled pastas: cheese ravioli (like the recipe), cheese tortellini, cheese & chicken tortellini or ravioli. I use whatever I have on hand and it always works.
