Baked Sweet Potatoes with Marshmallow Pecan Topping

0 Preheat the oven to 400 F.
1 Rub the sweet potatoes with the olive oil, then place on a sheet pan and sprinkle with 1/2 teaspoon of salt. Bake for 40 minutes, or until they can be easily pierced with a fork.
2 Remove the potatoes from the oven, then make a slit lengthwise in the center of the potato and squeeze the ends to open it.
3 Add 1 tablespoon butter, 1/4 teaspoon cinnamon, and 1/4 teaspoon salt to each potato, mixing it into the sweet potato flesh with a fork.
4 Top each sweet potato with 1/4 cup marshmallows and 2 tablespoons pecans. Return the sweet potatoes to the oven and bake for 15 minutes, until the marshmallows are browned, then remove from the oven and serve.
