Combine dressing mix with brown rice and butter. Stir in remaining ingredients, adding liquid gradually. Grease muffin cups and fill with dressing (an ice cream scoop makes it easy). A bit more liquid may be needed in the dressing to make it hold together. Bake at 350 degrees for 20-25 minutes, or until lightly browned. This stuffing may be baked in a greased casserole dish if preferred. Makes 12 muffins.
