Orange-Spiced Sweet Potatoes~by Kelsey

This recipe is from my Crock Pot Best-Loved Slow Cooker Recipes cook book.  I really like sweet potatoes, and this actually seems more like a dessert than a vegetable.  Maybe it's all the butter.  And sugar.  But it's really good and smells awesome!

Ingredients:
2 lbs sweet potatoes
1/2 cup packed brown sugar
1/2 cup butter, cut into small pieces
1 teaspoon cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon grated orange peel
Juice of one medium orange
1/4 teaspoon salt
1 teaspoon vanilla
toasted pecans (optional)
