In large bowl, combine pineapple, cranberry sauce, oranges, pecans, and marshmallows.
Gently fold in Cool Whip.
Serve immediately or cover and refrigerate until ready to serve.
Notes
Make sure that the pineapples and oranges arevery well drained before adding them to the bowl. If you have excess fruit juice in your salad, it will be a bit watery and not as fluffy. I like to strain off the juices in a colander, and then gently pat the fruit dry with paper towels or a dish towel so that it's nice and dry before stirring the salad together.
Thaw the Cool Whip in the refrigerator overnight. Do not thaw it at room temperature or it will melt and lose its fluffy texture.
Gentlyfold inthe Cool Whip, being careful not to stir too vigorously. Maintain as much of the air or "fluff" in the Cool Whip as possible, and don't damage the structure of the fruit in the salad.
If you want the pecans to stay crunchy, add them at the very end -- just before serving.
The salad is best when served within 1-3 hours of preparation; however, it can be made up to 24 hours in advance.
Garnish with extra marshmallows on top! Kids will go crazy for this side dish...
