Process frozen lemonade, hulled strawberries and 1 cup of water in a blender or food processor until berries are liquefied. This step can be done ahead of time and left in the refrigerator.
When ready to serve, pour the lemonade mixture into a punch bowl. Add the remaining 5 cups of water. Gradually stir in ginger ale. Serve over ice. Garnish with cut strawberries and/ or mint.
