It's Sunday when Mary Ann visits Christina and Carla Pallotta, two sisters who are the driving force behind Nebo Restaurant in Boston, MA, where they're preparing their mom's favorite recipes for visiting friends. Ricotta Gnocchi with Rabe and Pignola Nut Sauce, followed by Stuffed Breast of Veal, with Fontina Cheese, Polenta and Wild Mushrooms on the side. Great sisters. Lucky friends.
