Microwave Marshmallow Treats

Microwave margarine in a large mixing bowl for 1 minute until margarine is melted.

Add marshmallows and toss until well coated. Microwave 1 1/2 minutes or until smooth when stirred, stirring after 45 seconds.

Immediately add the cereal and mix thoroughly. Press into a 9 x 13-inch greased baking pan.

Allow to cool and cut into bars.
