I await the results with some consternation...
It turned out GREAT! I used two small boxes of sugar free lime jello, a regular thing of cream cheese, a regular sized container of sugar free cool whip and a third of a cup of lemon juice, because I forgot the lime juice.
I made it per instructions and poured it into a ground pecan crust.
Steve loved it and so did my eldest (very picky) jedi!
A great dessert. Thanks for doing the research!
