Combine the pineapple juice, orange juice, and fresh lime juice in a large punch bowl. Stir well to mix the flavours.
Add the pineapple chunks and orange slices to the punch bowl.
Just before serving, pour in the ginger ale or lemon-lime soda. This will add a delightful fizz to your punch.
Fill glasses with ice cubes and pour the punch over the ice.
Garnish with fresh mint leaves if desired.
