Sweet popcorn bars

This Recipe was so easy
1/2 cup unpopped popcorn
3 Cups Marshmallows
6 T Butter
M&M's - as much as you like :)

Pop the popcorn, melt the butter & marshmallows together, then pour over popcorn.  Once cooled add M&M's.  You can roll into balls if you like, or press into a 9x13 pan for bars (way easier, and less messy)
