In a blender, combine the pineapple chunks, half of the orange juice, and a generous amount of ice. Blend on high for about 30 seconds until smooth and creamy.

Pour the pineapple mixture into a pitcher or tall glasses. Rinse the blender for the strawberry layer.

In the now-empty blender, add the frozen strawberries, the remaining orange juice, and more ice. Blend until velvety smooth.

Spoon the strawberry mixture on top of the pineapple layer in glasses, creating a beautiful contrast.

Using a knife or skewer, gently swirl the layers together without fully mixing them.

Serve immediately, garnished with mint or fruit, and enjoy!
