7 Up Jello or GGjo's Jello

This is a favourite of everyones on my side of the family. My Grandma has made this for every get together we have had for as long as I can remember.

1 sm pkg of lime jello (jelly)
1 16 oz of apple sauce
1 8 oz of ginger ale (or 7 up)
cool whip (double cream whipped)

Heat the applesauce up in a pan till it is just bubbling.
Add the lime jello mix till desolved.
Take off heat and let cool slightly.
Add the ginger ale.
Put in a pretty dish and put it in the fridge till set.
Let sit over night as the harder it sets the better it is.
Top with the cool whip.
