If you want light, summery, I've got a recipe that's pretty good. I just tried it on Sunday and it goes in a graham cracker crust but if you doubled it, it could go into a bowl instead.
1 4 serving lime jello (sugar free)
2 T lime juice
2 T lime zest
2 cups cool whip lite (thawed).
graham cracker pie crust
Boil 2/3 c water, then add to jello. Mix until dissolved. Then take 1/2 cup cold water, add ice cubes to make 1 c. Add to dissolved jello and stir until cubes melt. Add 2T lime juice & 2 T zest. With a whisk, mix into cool whip. PUt in fridge for about 20 min until slightly set then put into pie crust. Makes about 6 servings
It's really good, light, fluffy and tastes somewhat like key lime pie. I'd double it if you're not putting into the pie shell. And, it's super easy!
