Strain the pineapple chunks and crushed pineapple.
Save the juice.

Notes
You can also mix the pineapple chunks and crushed pineapple (without the juice) to slightly melted vanilla ice cream. Mix well and refrigerate before serving.
You can use the reserved pineapple juice to make a smoothie. In a blender mix 2 cups chilled pineapple juice, ripe banana and 1 cup yogurt (curd).
