Delicately flaky pies made from fillo dough are common throughout the Mediterranean, Balkans and Middle East. Similar to small strudels, they can be filled with cheese, vegetables, minced meat and local spices. To prepare from scratch, these burek, spanakopita, tyropita and other fillo pie assortments can take a fair amount of time to prepare. So, a perfect solution is to serve our distinctive straight-from-the-freezer to the oven fillo appetizers, which are sure to impress. In spiral or sheet form, fillings include cheese, spinach and cheese, potato, leek and more.
