This is a recipe I found many years ago, and do not remember the source. My family calls it "Foam"
1 small container of small curd cottage cheese
1 small container of Whipped topping
1 small container sour cream
2 cups cut up fruit
1 small package jello (in a flavor to go with fruit)
Combine all ingredients in a medium size non-metal bowl. Stir to blend. Refrigerate for 2 or more hours in a covered bowl. Serve. (I have used larger containers, and the bigger box of Jello for crowds and it works too!)
