1 (5-ounce) jar pimiento cheese spread (Kraft)
1 (8-ounce) can pineapple tidbits, drained
1/2 (10.5-ounce) bag miniature marshmallows (about 3 1/3 cups)
1 (8-ounce) container frozen whipped topping, thawed
The key to this is mixing, mixing, mixing. Mix until you think it's mixed, and then mix it some more! You will see it getting fluffier and more cohesive. I find it's best if made the night before and refrigerated.
