The night before mix the coconut milk and chia seeds in a glass or plastic food container, stir, and refrigerate overnight.In the morning add the yogurt, shredded coconut, and coconut sugar to the container with soaked chia and stir together until everything is mixed well.Fill your serving bowls halfway with the chia pudding. (Note: I used small mason jars, but ramekins will work, too)Divide granola among the bowls, reserving a couple tablespoons for garnish.Cut mangoes into thin slices and divide them evenly among the bowls, reserving about ½ cup for garnish.Divide the rest of the chia pudding among the bowls, top with reserved mango slices, berries, and sprinkle with reserved granola.
