Preheat the oven to 475 degrees.
Place the sliced eggplant and potato slices on three baking pans.
Brush the eggplant and potatoes with olive oil and season both sides with salt, pepper and oregano.
Bake 15-20 minutes or until cooked and golden. Do not over cook the eggplant or it will fall apart and begin to melt. Make sure that it becomes golden on both sides.
Place the roasted potato slices on the bottom of a 9 x 13 inch baking pan. Use a deep pan. Sprinkle grated cheese over the potatoes.
Top with a layer of roasted eggplant slices and sprinkle grated cheese over them.
Top with the meat sauce and spread.
Make a final layer of roasted eggplant over the meat sauce and top with the béchamel sauce.
Sprinkle any remaining cheese over the sauce if desired.
Adjust oven temperature to 375 degrees.
Bake 45 minutes – 1 hour until the cream is golden brown on top.
Allow to rest for about 45 minutes before slicing so that the pieces hold their shape.
