Cut the pineapple in half, cutting out sections and scooping out the pineapple to make a boat.
From one half, take the fruit and cut into small pieces. Add 1 pint of blueberries and raspberries to the pineapple; mix and put back into the boat.
It’s optional to add strawberry slices to the mixture, or you can leave the strawberries whole and serve on the side.
Display the remaining fruit on a large platter with the pineapple boat and serve!
