I was given this recipe on another website by a friend. It is a miracle, it keeps me satisfied!

2 cups whipping cream
1 8 oz. pkg. cream cheese
1 box of sugar free jello, any flavor, I think cherry is the best
1 tsp. vanilla

Whip the whipping cream until stiff peaks form, set aside.
In another bowl mix the jello with 1/2 cup boiling water until dissolved. Add 1/2 cup cold water and set aside.
In a large bowl, cream the cream cheese and the vanilla. Slowly add the jello. Now add the whipping cream in small additions.
Refrigerate for 2 hours.
