Sara kicks off a visit to Rome with a street food tour led by American Ex Pat Katie Parla. They sample only in Rome treats like simple but delicious Mortadella sandwiches, Maritozzi pastries oozing with whipped cream, and Suppli, Roman deep fried rice balls. Then, they perform a Roman hat trick - three pastas starting with the same delicious base: Gricia made with guanciale transforms into Amatriciana by adding tomatoes or Carbonara by adding eggs. All are perfect, super easy weeknight meals. In her own kitchen, Sara makes her own delicious pasta - baked penne with prosciutto and Fontina cheese. Mangia! Recipes: Spaghetti alla Gricia; Bombolotti all'Amatriciana; Rigatoni alla Carbonara, Baked Penne with Prosciutto and Fontina.
