1 (12 oz.) pkg. semi-sweet chocolate pieces
1 c. chunky style peanut butter
4 c. (1 pkg. 10 1/2 oz.) mini marshmallows

Nuke peanut butter and chocolate in 2 quart bowl on medium (50%) 2-4 minutes or until melted. Stir after each minute. Fold in marshmallows. Pour into greased 9 inch square pan; chill until firm, cut into squares. Serve with napkins, they are good and messy!
