Preparation -
Spray an 8" x 8" square cake pan with non-stick cooking spray; set aside. In a medium size bowl, mix the oats, brown sugar, margarine, and honey together. Microwave on full power for 5 minutes, stopping to stir 2 or 3 times.  Spread the mixture evenly in the prepared cake pan. Place in the refrigerator to cool. In a microwave-safe bowl, combine the chocolate chips and peanut butter. Microwave on full power for 1-1/2 minutes or until the chocolate chips are melted, stopping to stir halfway through the cooking time. Spread the melted chocolate mixture over the chilled oatmeal mixture in the cake pan. Refrigerate until the chocolate hardens. When completely chilled, cut into squares.
