You have to make this one the day before. I know sour cream in a fruit salad sounds strange, but if you are a fruit salad fan, you will love it!
1 can chunk pineapple, drained
1 can mandarin oranges, drained
1 cup coconut flakes
1/2 bag mini marshmallows
8 oz. sour cream
Mix all ingredients in a bowl. For best results, refrigerate for 24 hours before serving.
