Dissolve the yeast in warm water and add the flour, salt, and sugar. Knead everything into a firm dough, place the dough ball in a bowl, cover with a dish cloth, and let it sit for 1 hour. Form the dough ball into a 1-inch thick roll and cut off ½-inch slices. Roll these slices into small balls, cover them, and let sit for 10 minutes. Now roll each of the balls into an oval shape. Grease and flour a sheet pan, place the pita pockets on the pan, and cook at 475°F for about 8 to 10 minutes. Once you have removed the bread from the oven, reduce the heat to 350°F for the schnitzel tower that will soon follow.
Cut the pork tenderloin into equal slices and flatten them. Season each pork cutlet with lemon juice and salt. Use a food processor to turn the stale bread rolls into bread crumbs.
Bread the pork cutlets and fry them in oil.
Cut 3 lemons in half, place three halves in the center of a pan, and stick a wooden skewer through each lemon.
Assemble the meat spit with alternating layers of schnitzel and cheese.
Cut the potatoes and fry them in hot oil for 4-5 minutes. Top off the wooden skewers with the 3 remaining lemon halves, place the finished fries in the pan around the schnitzel tower, place the pan in the oven, and bake at 350°F for 10 minutes. In the meantime, heat the ready-made béchamel sauce.
Once the meat has slightly cooled, use an electric knife to shave pieces off the schnitzel spit.
Fill your pita pocket with lettuce, fries, and a few schnitzel pieces, and drizzle some béchamel sauce on top for a truly unforgettable sandwich.
