In microwave, melt chocolate chips in a small bowl for 15 seconds at a time, stirring in between, for about 2 minutes or until melted.
Immediately dip one side of each marshmallow into the melted chocolate, then set the undipped side on a piece of parchment & sprinkle with nuts.
To make skewers, add a piece of melon, followed by a one-bite brownie, and marshmallow. Continue this order until skewers are full and place on serving platter.
Use a culinary torch to toast the marshmallows.
