In a large bowl, combine bananas, blueberries and mango. To serve, spoon one-third of the fruit evenly into four parfait glasses or 8-ounce clear drinking glasses. Top with half of the bread cubes. Spoon half of the yogurt mixture on top of the bread cubes. Repeat layers once, using half of the remaining fruit, all of the remaining bread cubes, and all of the remaining yogurt mixture. Top evenly with remaining fruit. Drizzle with honey. Serve immediately.
