Well, in their head they were probably just making a version of pastitsio, tailored to please the silly locals:
250 gram spaghetti, cooked
1 onion, chopped finely
1 teaspoon minced garlic
1 cup of minced meat
2 tomatoes, chopped
salt and pepper to taste
1 tablespoon of parsley, chopped finely
1 tablespoon butter (or margarine)
2 tablespoons cake flour
1 and a half cups of milk
1 egg, beaten
1 cup of grated cheddar cheese
1/4 cup of parmesan cheese
Using a large frying pan, saut the onion and garlic. Add the meat and brown.
Add the tomatoes, salt, pepper and parsley. Simmer until cooked through and the mixture has the consistency of a sauce.
Using a greased oven proof dish, layer the cooked spaghetti and the mince in the dish.
Use the butter, flour and milk to make a white sauce. Add salt and pepper to taste.
Remove from heat and let the white sauce cool.
Stir in the egg and grated cheddar cheese. Pour over the mince and spaghetti. Sprinkle the parmesan cheese on top.
Bake for 45 minutes at 350 degrees Fahrenheit.
