I found this recipe. It's called "Weight Watchers Easy Tasty Frozen Pie". It has two ingredients.

You need an 8 ounce (226.79 g) container of fat-free Cool Whip (or another brand of whipped cream type dessert topping) and one 6 ounce (170.09 g) container of light yogurt of any flavor. Mix those together and pour into a pie plate, with or without a pie crust, and stick it into the freezer.

I haven't tried it yet. I'm putting it here so I remember where it is. Sounds like it would be perfect for summer! If I like it, I think I will be making this pretty often.

Here's a link with a picture and the nutritional information.

This sounds really good and very easy to make. This would be the perfect alternative to cream pies. I would really like to try this with cherry yogurt since it is my favorite. I wonder if you could use Greek yogurt instead, because I think it has a better flavor than traditional yogurt.

That sounds lovely!

6 oz. of yogurt doesn't seem like it would be enough to flavor the whole pie. It is intriguing, though. I'll have to give it a try. Might be even better with some added fruit, too.
