Confetti Popcorn Balls

1 package microwave popcorn
1/2 cup M&Ms or small gumdrops

In large greased bowl, combine popcorn with candy and peanuts. Place marshmallows and margarine in microwave-safe container. Microwave on HIGH for 1 1/2 to 2 minutes or until melted and smooth, stirring once halfway through cooking. Pour marshmallow mixture over popcorn mixture; toss until evenly coated.
