Preheat oven to 400 degrees F. Coat a baking sheet with cooking spray. Place potatoes on baking sheet. Bake 50-55 minutes or until very soft.

Step 2

Cool potatoes slightly, then slice in half lengthwise. Scoop out sweet potato center, leaving a thin layer inside, and place in a medium bowl. Add milk and mash until smooth. Stir in brown sugar, cinnamon, salt, and pineapple; mix well.

Step 3

Spoon potato mixture evenly into each potato shell and sprinkle with nuts. Place on baking sheet and bake for 15-20 minutes, or until heated through.
