Rice Christmas Treats

Here's a good holiday spin on a classic recipe- rice krispie treats!  Makes about two dozen treats.

Ingredients:
1/4 cup butter
6 cups mini marshmallows
green food coloring
6 cups rice krispies cereal
1 cup red and green plain M&M's candy

Kitchen gear: 
13 by 9 inch pan
Non-stick cooking spray
Wax paper

Directions:
1.  Place the butter in a large microwave safe bowl.  Microwave for 45 seconds or until melted. Add marshmallows and stir until they are coated evenly with butter.  Microwave for 45 seconds.
2.  Stir in 6-10 drops of food coloring.  Heat another 45 seconds in the microwave.
3.  Add rice krispies cereal, stir until well mixed.  Spray the inside of the 13 by 9 inch pan with non-stick cooking spray, then scrape the rice krispie mix into the pan.
4.  Tear off a sheet of wax paper large enough to cover the pan.  Spray lightly with the cooking spray and use this to press the rice krispie mix into an even layer in the pan. 
5.  Remove the wax paper and sprinkle M&M's over the top of the rice krispie mix.  Use the wax paper sheet to press M&M's into the rice krispie mix.
6.  Let the mix stand for a couple hours.  Use a large knife to cut the mix into bars or triangles.  Store at room temperature in an air-tight container.
