01 - Pour the chilled lemon-lime soda and non-alcoholic ginger beer into a large pitcher. Mix gently to combine without losing carbonation.
02 - Stir in the green food coloring and freshly squeezed lime juice. Continue stirring until the color is evenly distributed throughout the mixture.
03 - Taste the mocktail and adjust the lime juice for tartness or add additional food coloring drop by drop until the desired vibrant green shade is achieved.
04 - Fill four pint glasses with ice cubes if desired. Pour the green mocktail evenly into each glass, leaving about half an inch from the rim.
05 - Place a lime wheel or wedge on the rim of each glass. Add a fresh mint sprig to each drink and serve immediately while cold and effervescent.
