The recipe is really easy and takes minutes to make. The ingredients can be modified to cut down on the calories and fat. Try substituting low fast graham crackers and light cream cheese. I'm not sure if sweetened condensed milk comes in a light version but if this ingredient could be subbed out, that would cut down on a lot of the calories.

Ingredients:
1 pkg of graham crackers
1/4 cup granulated sugar
5 Tablespoons of butter
8 ounces cream cheese, softened
1 can of sweetened condensed milk
1/2 cup key lime juice (Nellie & Joe's) - can adjust amount for tartness
Instructions:
For the pie crust, crush the graham crackers in a baggie, add the sugar and shake. Add melted butter, pour into spring form pan or pie dish and press to the sides and bottom. Bake at 375F for 8 minutes (I put it in for 10 minutes because I love it when the crust is a little bit more caramelized and crispy)
For the filling, mix cheese with sweetened condensed milk, add key lime juice until blended. Pour into baked crust and chill in the fridge.
You can add anything to the top you think will taste good. Barb's version had fresh made whipped cream and sliced kiwi. I made this dessert for a dinner party this past Saturday and it was very well received. Mine had raspberries and blueberries.
Hope you enjoy it as much as I did!
