Lime Jello Salad. The ingredients make it sound like the grossest thing ever made, but don't knock it until you try it. At our house it is simply called, "Green Stuff," and it is requested for every holiday under the sun, but I am expected to make 2 batches of it for Thanksgiving. We have used walnuts, but now it is usually slivered almonds. I also make one without nuts for my ds with a tree nut allergy.
(Who in their right mind would think that mayo, cream cheese, and cool whip would taste good together??!)
http://www.cooks.com/recipe/9c4gj0l0/congealed-salad.html - is close, but the proportions are not quite right. I think it's 2 small lime jellos, 1 cup boiling water, 1 package cream cheese, 1 can crushed pineapple including juice (we like pineapple tidbits instead sometimes), 1 cup mayo, 1 cup cool whip, and nuts are optional. I think that's it, but don't quote me on it. LOL
