01 - If desired, moisten the rims of your serving glasses and dip them into green sanding sugar to create a festive border. Set the prepared glasses aside.
02 - In a large punch bowl, gently pour in the chilled lemon-lime soda and pineapple juice. Stir lightly to ensure they are well combined.
03 - Carefully place scoops of lime sherbet into the punch bowl. Allow the sherbet to float on the surface and begin to melt, forming a frothy, creamy layer.
04 - Garnish the punch with thin slices of lime and fresh mint leaves, if using. Serve the punch immediately in the prepared glasses.
