Green Jello Salad

"This is a refreshing jello salad that is a staple of our family get togethers. This is a recipe from my Grandmother. We now joke about making this jello months in advance (don't do it!!), because my Grandmother brought it for a family dinner and said she had made it weeks before - we could not eat it, but did not have the heart to tell her. It was the beginning signs of Alzheimer's :( for her. I hope she is not spinning in her grave since I am sharing this recipe. We miss her and think of her when we have this jello for Thanksgiving and Christmas...."
