Here is a recipe I've made numerous times for Mousaka.

Ingredients:
2 Med Eggplant
Oil for frying

Meat Sauce:
1 Med Onion chopped
1 LB Ground Beef
1 Tsp Crushed Garlic
1/2 Tsp Oregano
1 Cup Tomato Sauce

Cut off ends of Eggplant. Do not peel. Slice the long way and sprinkle with salt. Rinse off after a half hour and pat dry. Fry the eggplant slices till golden brown on both sides and set aside.

Saute the Onion in the oil then add all the other ingredients Cook till the meat is cooked and set aside.

White Sauce Ingredients:
2 Tbl Margarine
2 Tbl Flour
1 C Water
2 Eggs
Salt & Pepper to taste

Melt Margarine & add the Flour. Stir for a few minutes on low heat. Add the water and cook till it thickens. Beat the eggs and add a drop of the Flour mixture to the beaten eggs. Now slowly add the eggs to the flour mixture and stir till smooth. Add the salt & Pepper to taste. Cool mixture. Now you are ready to assemble the Mousaka.

In a 9x13 pan, spread a third of the eggplant. Cover with half the Meat Sauce.Next another third of the Eggplant & the remaining Meat sauce. Next add Half the White sauce, then the remaining Eggplant and top with the remaining White Sauce.

Bake at 350 for about 40 Minutes.

Let me know how it came out.
