    Great recipe! Susan, I wanted to say that the 0.3 is correct. The sugar-free Jell-O 0.3 ounces and regular Jell-O is 3.0. You must’ve use the regular.

    This is a wonderfully easy, tasty & healthy dessert! My only comment is that the amount of gelatin is incorrect -- since it says "one packet", I used the smallest size, which is 3.0 oz., Not 0.3 oz. -- just a typo when it was posted, I'm sure. I used the full 3 Oz. packet and it came out fine :)

    This is an easy, wonderful, light dessert! I have made key lime, raspberry, and strawberry so far and plan to try more different flavors! I used regular gelatin and low-fat greek yogurt and light whipped topping. I didn't add all the whipped topping to the pie so I could put it on the pie along with fresh fruit when I served it. DELICIOUS!

    This recipe is for me. I followed the directions to the letter and it was fabulous. I made a low cholesterol graham cracker crust without butter to go with it. We put one of the pies in the freezer and it was a lovely frozen desert.

    This is a delicious pie. I was first introduced to it at a Weight Watcher meeting. It's a treat for those avoiding sugar.

    Loved the crust. Made it with brown sugar. The filling wasn't very tasty. Added lime juice which helped a little. Will add more next time I make it. My family loved it as is and ate all of it.

    Love this pie. It tastes great and only takes 10 minutes to make. Sometimes I just make the filling and sprinkle crushed graham crackers over it.

    Love this easy, flavorful, summer recipe! If you are a key lime pie snob, it’s obvious from the ingredients that it is not going to be “true “ key lime pie; however, call it creamy lime flavored pie! Either way, mine came out delicious and it is great to serve on a warm summer evening. I used Chabani key lime flavored yogurt, just because I love the flavor of this yogurt by itself! Stick it in the freezer for about an hour before serving, and it’s like eating an ice cream pie! Yummy!
