Here's a quick one that I invented last night:
Peal, core and slice into small pieces four apples (or more if they're small). mix apples with sugar and flour and let set in a covered bowl for about an hour. Unroll a tube of Pillsbury crescent rolls, use your fingers to seal the perforations to make one sheet of dough. Place the apples on one half of the dough to about 1/2 inch from the edges. Fold over the other half and seal. Bake according the the directions on the package. Not quite an apple streudel, but pretty good for somethng that takes no time at all to fix.
