2 cups semisweet, bittersweet, or milk chocolate chips
1 1/2 cups assorted nuts (peanuts, almonds, pecans, walnuts, etc)
Line rimmed baking sheet with foil. Melt chocolate in the microwave, stirring every 20-30 seconds. Mix together melted chocolate and nuts. Spread chocolate/nut mixture onto pan, creating a 12×9 inch rectangle. Refrigerate until set, about 20 minutes.
Break bark into medium-sized pieces and enjoy.
