This recipe was on the box of Pistachio JELL-O. They called it "Watergate Salad". It was really good and quick and easy.
1 pkg (4-serving size) JELL-O Pistachio flavor fat free sugar free
1 8-oz can crushed pineapple in juice, undrained
1 cup vanilla low fat yogurt (I used non-fat greek yogurt)
2 1/2 cups thawed COOL WHIP whipped topping
Stir dry pudding mix, pineapple and yogurt in large bowl until well blended. Gently stir in 2 cups of the whipped topping. Cover and refrigerate at least one hour. Serve topped with remaining whipped topping.
