Moussaka is made differently depending on the country the Greek version usually has layers of meat and eggplant topped with a Bechamel sauce, kind of like a lasagna. In Serbia and Bulgaria, they use potatoes instead of eggplant. There are even vegan versions that substitute mushrooms for the meat. Years ago before I was vegan, I used to go to a Greek restaurant in Tribeca and I would get the moussaka. There they made it with meat, eggplant and potatoes so thats how Ive always known it sort of a Greek Shepherds Pie, if you will. So I was thinking of making my own vegan version of moussaka with just eggplants and potatoes but I still wanted a burger. Then I thought, why not a Moussaka burger??
