2 ounces pizza dough
Flour, for rolling surface
Extra-virgin olive oil
1/2 cup basil pesto
2 cups ricotta cheese, preferably whole milk
4 tablespoons freshly grated Parmesan
Salt and freshly ground black pepper
Entertaining Notes: You don't need to make your own dough, not for a party of 8 people. Buy it from a local pizzeria. To work ahead, roll the dough into rounds about a half hour before your guests arrive and stack them, dusted with flour, at room temperature, between sheets of parchment paper.
