01 - Preheat oven to 350°F (180°C) and line a baking sheet with parchment paper.
02 - In a medium mixing bowl, whisk together egg, coconut yogurt, honey or maple syrup, vanilla extract, and sea salt until fully combined.
03 - Arrange bread slices on the parchment-lined baking sheet. Using a spoon, gently press the center of each slice to create a shallow well, leaving a raised border.
04 - Spoon the coconut custard mixture evenly into the wells of each slice.
05 - Bake in the center of the oven for 10 to 12 minutes, or until the custard is set and the bread edges are crisp and golden.
06 - Remove from the oven and allow to cool briefly. Top each toast with mango, pineapple, kiwi, shredded coconut, and lime zest.
07 - Drizzle with additional honey or maple syrup if desired. Serve immediately.
