This is an Egyptian favorite. A ground meat mixture between two layers of macaroni smothered in a creamy bachamel sauce. You can use any type of pasta you like. The most common are Penne (which is my favorite) angel hair, spaghetti or elbow macaroni. I have a glass dish that is 8x11 and I prefer to bake in this dish because I like it to be a little thick, but if you like it to be a little thinner than that you can opt for the larger 9x13.
