With sharp knife, make deep cut along inside curve of each banana. Press ends of peel to open.

Fill each banana evenly with chocolate and peanut butter chips.

Place one banana in a microwave-safe dish. Microwave it on High for 45 seconds. Or for a camping treat, wrap each banana in heavy-duty foil. Place in campfire coals or on grill. Heat about 5 minutes or until bananas are tender and chips are melted. Sprinkle with peanuts.
