Stuffed Miniature Pumpkins

I was wondering what to do with all those cute little pumpkins I had left over from Halloween, when I remembered that years ago, my friend Frieda had this idea to stuff miniature pumpkins for one of our PTA fundraiser cooking classes.  This dish makes such a beautiful presentation and I thought this updated combination of rice with mushrooms tasted great.  There are endless variations, using different kinds of rice, vegetables, nuts, herbs, or dried fruit.  I prefer to use those little round pumpkins rather then the flatter ones, since they have a larger cavity to stuff.
