Breakfast Pizza with Fresh Berries and Mascarpone

Name: Breakfast Pizza with Fresh Berries and Mascarpone
Ingredients: 1 12-inch pre-made pizza crust (I use Whole Foods organic pizza crust); 2 tablespoons melted butter; 4 tablespoons granulated sugar mixed with 1 teaspoon ground cinnamon; 12 ounces (about 1 1/2 cups) mascarpone (you can cheat and use regular cream cheese, it just won't taste as good!); 2 tablespoons lemon juice; About 2 cups of whatever berries are available - I used strawberries, blackberries and raspberries, but you could also add blueberries, or even thinly sliced peaches; tiny mint sprigs
