Strudel:

1 package frozen strudel dough

4 tablespoons butter, melted and cooled slightly

desired filling—canned apple pie filling or cherry pie filling, use approximately 1 cup of filling, combined with ¼ cup toasted bread crumbs

You can also make your own filling with fresh fruits
Remove frozen dough from freezer, open outer package, leaving dough inside paper wrapper and let it come to room temperature. When soft, open the delicate dough carefully, and unfold until all sheets are completely open and flat. Place a dampened tea towel over the stack at all times while you are working with the dough. On a non-stick cookie sheet, place 1 or two sheets of dough, smooth out carefully, and brush quickly with melted butter; repeat until you have at least 8 layers of dough. Spoon filling along the long edge closest to you, leaving about 2 inches at each end. Fold the ends toward center and begin rolling the dough away from you. It should rest on the final seam. To seal the seam, use a slightly moistened finger and rub the seam closed. Roll strudel, if necessary, to get the seam on the bottom. Using a sharp knife, cut diagonal slices about 1 inch apart just through the first few top layers of the dough. Brush top with melted butter. Place tray in freezer while you preheat oven according to package directions. Strudel can be wrapped in plastic wrap (and a freezer bag) until needed. Bake strudel in a preheated 400 degree oven, placing rack in top third of oven, until golden brown. Let cool slightly, sprinkle with powdered sugar, then slice and serve. Vanilla ice cream is a great complement to strudel.

A nice variation--Apple Strudel Bundles (Batyuk)
To make my own filling I use 8 Granny Smith apples, peeled and chopped into 1/4 inch or so pieces. Add sugar--just eyeball--about half a cup, and cinnamon. Stir well and let sit for about 1/2 hr. until liquid can be drained. Taste to see if it needs more sugar. If it's too sweet, add a few drops of lemon juice. Melt butter--it takes about 2 1/2 sticks total. When sheets are completely defrosted begin to assemble.

Layer 5 sheets of dough, buttering each sheet, and place a scoop of filling in the center of the rectangle. Add a teaspoon of ground nuts and one teaspoon toasted bread crumbs. Pull up two opposite corners, and fold in the sides and pick up the other two opposite corners and form a bundle, twisting slightly to get the bundle shape. Brush the outside with butter. Place on a floured tray in freezer. One package of dough will make 8 bundles (allowing you to mess up one or two sheets like I usually do). When frozen solid, place in zip lock bag. To bake, preheat oven, to 400. Place in top third of oven. Cover loosely just on top to prevent the bundle tops from burning. When the bottom of the bundles is golden brown, remove the foil and continue to bake until the tops are lightly browned too. Let cool slightly, then sprinkle with powdered sugar.
