Combine a large package (6 oz.) of jello (any flavor works) with a can (20 oz.) of crushed pineapple. (I don't recall ever draining the pineapple first, but this time the end result was a little soft, so I think next time I'll drain it.) Stir in a carton (16 oz.) of cottage cheese and some cool whip (1-2 cups). Serve.It added a nice touch of green to our St. Patrick's Day meal.
And the next day I added some sliced bananas to the leftover jello and that was delicious.
