01 - Preheat oven to 350°F. 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 a pinch of salt until smooth and creamy.
03 - Arrange bread slices on the prepared baking sheet. Using the back of a spoon, gently press down the center of each slice to form a shallow well, preserving the outer edges.
04 - Spoon the custard mixture evenly into the wells of each bread slice.
05 - Bake for 10 to 12 minutes, until the custard is just set and the edges of the bread turn golden.
06 - Remove from oven and allow to cool briefly. Top each toast with diced mango, diced pineapple, sliced kiwi, shredded coconut, and lime zest.
07 - Drizzle with extra honey or maple syrup if desired, and serve immediately.
