Measure the chia seeds, coconut water, coconut milk, passion fruit, and orange juice into a bowl.
Whisk for 5 seconds to incorporate the seeds and liquids.
Allow to stand for 5-10 minutes. Whisk again for 5 seconds.
Transfer to the fridge to activate for at least 2 hours or ideally overnight. You can stir the chia seeds a couple of times throughout so they are evenly absorbed by the liquid.
To finish and serve
Cut the pineapple, papaya and mango into small dice. Mix all together in a bowl with the passion fruit.
Add half of the fruit dice to the chia seed mix, along with some orange and lime zest to season.
Give the Tropical Chia Seed mix a final stir and transfer to serving bowls or glasses.
Garnish with the remaining mango, pineapple, banana, papaya, and passion fruit seeds.
