Line a 9x9-inch pan with parchment paper. Mix together the Dry Roasted Peanuts (2 cup) and Mini Marshmallows (7 cup) in a large bowl and set aside.
In a microwavable measuring cup, add Semi-Sweet Chocolate Chips (2 cup) and Butter (2 tablespoon). Heat in the Panasonic Microwave Oven on high for 60-90 seconds. Remove, stir, then microwave again for another 60-90 seconds.
Remove from microwave, and stir until chocolate is completely melted. Let cool 5 minutes, then stir into the marshmallow peanut mixture until completely coated.
Spread into prepared pan, and chill for 2 hours in the refrigerator. Cut into squares, and enjoy! Cooking results may vary depending on microwave oven used.
