Top the watermelon slices with the Sweetened Yogurt, strawberries, blueberries, pomegranate, kiwis and mint leaves. Drizzle with the Chocolate Ganache and top with semisweet and white chocolate shavings. Cut into wedges.
Mix the yogurt and sugar together in a bowl.
Put the chocolate pieces in a medium bowl. Heat the cream in a small saucepan until very hot. Add the vanilla, then pour over the chocolate pieces. Stir to completely melt.
