Step 1

Add the cranberries to a food processor. Pulse until they're well-chopped but not mushy. Pour them into a bowl and stir in the sugar. Cover and refrigerate them overnight (or for at least 2 hours).

Step 2

Mix in the drained pineapple, marshmallows, and pecans (if using). Gently stir the Cool Whip into the cranberry mixture with a rubber spatula. Cover and refrigerate it for at least 2 hours.

Step 3

Serve it and enjoy!
