Slice each papaya in half lengthwise. Scoop out the seeds with a large spoon and discard.

In a small bowl, combine yogurt and chia seeds. Stir to combine.

Divide the coconut yogurt mixture equally between the papaya halves.

Top with blueberries, raspberries, blackberries, and toasted coconut flakes.

Garnish with a sprig of fresh mint or basil and serve immediately.
