Place the white chocolate in a microwave-proof glass bowl, uncovered, & melt it in that appliance on 50% power, starting with 1 minute, then stirring & adding 20- to 30-second increments until completely melted. BE SURE TO WATCH IT CAREFULLY ~ Once it is totally melted, proceed.

Add nuts & berries, stirring to combine, then spread this mixture to the thickness desired on a parchment-lined baking tray.

Refrigerate 5 to 10 minutes, then remove the tray & let it set in a cool place.

When completely cooled, cut or break into pieces & store in an airtight container.
