For each banana boat peel back a long strip of banana peel along the inside curve, leaving one end attached to the banana.
Scoop out about one-half of the banana and fill with a large marshmallow, cut in half, and two or three pieces milk chocolate or several semi-sweet chocolate baking bits. Replace the strip of peel. (If peel has broken off, place peel back on the banana and secure in place by wrapping ends of banana with foil.)
Place filled bananas in coals for about 15 minutes or until chocolate and marshmallows are melted and skins are black.
