In a shallow roasting pan, combine popcorn, pretzels and cashews; set aside. In a heavy medium size saucepan, melt candy coating over low heat, stirring constantly, until smooth. Remove from heat. Stir in 1/2 cup of the crushed candy. Pour melted mixture over popcorn mixture. Stir gently to coat. Spread onto a large piece of foil. Sprinkle with remaining 1/2 cup crushed candy. Cool and break into pieces. Store in airtight container. Makes 24 servings.
