Make The Meat Sauce
In a cooking pot over medium high heat, brown the meat (beef or lamb) for about 10 minutes. Add the onions and gently mix for another 10 minutes. Add the tomato sauce, garlic, parsley, and all the spices listed under “Meat Sauce.” Lower the heat to medium low, cover the pot and all the meat sauce to simmer down for about 10-15 minutes (Make the Béchamel Sauce at this time) and then take heat off, allow to cool slightly, add the beaten egg to the meat mixture, blending well into the meat, and set aside.
Make The Béchamel Sauce
Melt the butter in a cooking pot over medium high heat. Add the flour and mix using a whisk. Slowly add the milk while stirring with a whisk. Increase heat to high. Once the béchamel starts bubbling, lower the heat again to medium high and add the water. Continue stirring till the sauce is thick again. Turn heat off and add salt and nutmeg. Set aside.
