Key lime pie

Does anyone have the recipe for the key lime pie with yogurt and sugar free jello?  My Alzheimer's has kicked in and I forgot how to make it,   I "think" its sugar free lime jello, 2 lime  yogurts , pie shell and ????? maybe coolwhip, not sure. 

Thanks,

Robin

Robin-I don't know if this is exactly what you're looking for but I got this out Weigh****chers, Simply The Best.  Luscious Lemon Pie(can sub Lime)

12 low-fat graham crackers, crushed fine
4 tsp reduced fat margarine
(mix these & spread into pie plate, bake @350 6-8 min, cool)


1sm box sf ff lemon jello
1/2c boiling water
1 sm box sf ff instant lemon pudding mix
2c sf ff lemon yogurt, divided
1c skim milk
1 c plain ff sf yogurt

In a small bowl, combine jello & boiling water;stir til dissolved(about 2 min). In a large bowl, at med. speed, beat together pudding mix, 1c lemon yogurt, milk, & the plain yogurt. Add the jello mixture & stir til combined. Pour into crust. Cover & refrigerate til firm. Top each slice w/remaining lemon yogurt & fat-free coll whip. Serves 8.

Where can you buy sf ff Lime pudding mix at ?
Thanks
Deb

Oops-I forgot to add: SF FF Lime pudding isn't available(as far as I know) so sub either sf ff lemon or sf ff vanilla but use lime everything else. Does that make sense? Good catch Deb! Thank you!!
