Don’t let phyllo dough’s fussy reputation put you off: our method of brushing olive oil and sprinkling breadcrumbs between the layers makes this tart actually quite simple to assemble, and helps keep it healthy. It can be served as a main course or cut into smaller pieces and enjoyed as an appetizer. Thaw frozen phyllo in its package at room temperature for 2 hours or in refrigerator for at least 8 hours or overnight. EatingWell Magazine, June 2007. Always remembering to keep it covered with a damp cloth towel.
