This recipe for Pao de Queijo, or cheese bread balls, is the perfect appetizer. The dough is made by mixing Minas and Parmesan cheese with yucca flour and some other ingredients, before being scooped into small balls and then baked for 15 minutes. When they come out of the oven they are soft inside with a gooey texture that is simply addicting. Leticia says that she gives these to her kids for breakfast.
