To make 25 servings of white trash snack mix, combine 3 cups of Cheerios toasted oat cereal, 3 cups Rice Chex, 3 cups Corn Chex, 2 cups small pretzels, 2 1?2 cups salted mixed nuts, and 16 ounces M&M's in a large bowl. Melt 11 ounces of white chocolate chips, stirring occasionally. Pour melted chocolate over the dry mix and fold it over until the mix is well covered. Spread over parchment. Once the mix has cooled, break into pieces.
Melt the chocolate in a microwave safe bowl or in a double boiler, stirring often, being careful not to burn the chocolate or your skin. After mixing the dry mix and melted chocolate and spreading it over parchment, let the mixture cool, set and harden before breaking it into pieces.
Alternate recipes include Bugles, Fritos or other corn chips, broken Oreos, and white chocolate almond bark or candy melts. Vary the amount of dry ingredients and chocolate chips for preferred taste and texture.
To reduce cleanup, spread the dry mix on parchment paper, and poor the melted chocolate directly onto the parchment paper. Use a spoon or spatula to spread the melted chocolate over the dry mix for a more even coating.
