Place 1 tablespoon brown sugar, 1 tablespoon butter, the water, cinnamon, and nutmeg in medium bowl. Microwave at HIGH (100%) until butter is melted, 1 to 1 1/2 minutes, stirring after half the time. Add marshmallows; toss to coat.

Top sweet potato mixture with marshmallows. Microwave at HIGH (100 %) until the marshmallows are melted and potatoes are heated through, 2 to 4 minutes. Sprinkle with pecans.
