Run a thin knife around inside of each orange half to loosen pulp. Scoop pulp from rind and remove membranes from orange sections. Gently peel away and discard inner membranes from orange halves, leaving rinds intact to form 12 dry cups.
Add orange pulp to potato mixture, mixing thoroughly. Spoon into rind cups, dividing equally. Bake 20 to 30 minutes in preheated oven. If desired, place mini marshmallows on top of mixture and return to oven until marshmallows are browned. Makes 12 servings. Enjoy!
