Chocolate Pizza

1 premade thin pizza crust
1/4 cup Nutella
1/2 cup semisweet chocolate chips
2 tablespoons milk chocolate chips
2 tablespoons white chocolate chips
2 tablespoons chopped hazelnuts, toasted

Position the oven rack on the bottom of the oven and preheat to 450 degrees F. Bake for 8-10 minutes, or until pale golden brown. Immediately spread the Nutela over the pizza then sprinkle all the chocolate chips over. Bake just until the chocolate begins to melt, about 1 minute. Sprinkle the hazelnuts over the pizza. Cut into wedges and serve.
