My mom got this recipe from her aunt a loooong time ago. This recipe makes a lot. So you could probably cut half the cottage cheese.
1 small Cool Whip (8 or 12 oz, depending on how creamy you want it)
1 Can Crushed Pineapple (20oz)
2 Cottage Cheese (32 oz)
1 box Lime Jello (6 oz)
Drain Pineapple. Add all ingredients to a large bowl and mix well. Serve.
