Apple Strudel

Preheat oven to 350° and line a baking sheet with parchment. In a large bowl, stir together apples, cinnamon, lemon zest, sugar, salt, and raisins. Fold in breadcrumbs. On a tea towel, place down one sheet of filo and brush with melted butter. Lay another sheet on top, then brush with more butter. Repeat until you’ve used all filo sheets. (Don't butter the top.) Turn filo dough so the short side is facing you. Pile apple filling on the third of dough closest to you, leaving a 2" border on each side. Using the tea towel to help you, fold bottom of filo over apple filling. Fold over side edges as well, then roll away from you until filling is enclosed and the seam is on the bottom. Transfer to prepared baking sheet and brush with melted butter. Bake until golden brown, about 35 minutes. Let cool to room temperature, then sprinkle with powdered sugar and cinnamon before serving.
