Using several large bowls, combine the popcorn, cereal, and chips.
In a saucepan, heat the white morsels until melted and smooth. I used medium-high heat, stirring almost constantly, and didn't have any scorching. Spoon the melted morsels over the popcorn mixture and toss to coat.
Transfer to baking pans/dishes and allow to cool.
Break into chunks and put into serving bowls.
