Add the cottage cheese in a Trifle Dish or clear bowl.

Next, using a rubber spatula, stir in the cool whip.  This will add a nice sticky base for the marshmallows, which come next.

Next, stir in the mini marshmallows.

Toss in the chopped walnuts. 

Stir in the crushed pineapple. 

If you are serving this as a dessert, stir in the sugar. 

Stir in the Lime Jello.  

If you like you can decorate with some cherries.  

Refrigerate several hours or overnight to set.
