Combine the juice from the canned pineapple tidbits, coconut oil, maple syrup, lemon juice, cornstarch, and water in a small saucepan. Bring the mixture to a boil, then reduce the heat and simmer, stirring until thickened.
Remove the dressing from the heat and cool completely. Once cooled, stir in the vegan Greek yogurt and refrigerate until ready to be used.
To assemble, add all the fruits to a bowl and drizzle the yogurt dressing on top.
Right before serving, gently toss the dressing with the prepared fruits until well coated.
Notes
Get creative with your tropical fruit salad and add other fruits to the mix! Go for a variety of colors, textures, and flavors, and add fruits like fresh papaya, mango, cantaloupe, pomegranate, and blackberries.
If you prefer a less indulgent take on your tropical fruit cup, swap the yogurt dressing for a simple honey lime dressing. The mixture of vegan honey, lime, and lemon juice adds just the right amount of sweetness and tanginess.
This tropical fruit salad tastes best freshly made, but it's also delicious when chilled. For leftovers, store the fruit salad in an airtight container in the fridge for 1 to 2 days, as the fruits have a high water content that can thin out the creamy yogurt dressing.
