The main ingredient in a traditional Greek dish called "moussaka" is eggplant. Moussaka is a layered casserole dish that typically features eggplant, ground meat (usually lamb or beef), and a creamy béchamel sauce. The eggplant is sliced, often salted, and then fried or baked to enhance its flavor and texture. In addition to eggplant and meat, the dish can contain other vegetables like potatoes and tomatoes, depending on regional variations. Moussaka is a beloved staple in Greek cuisine, often served at family gatherings and special occasions. Its combination of flavors and textures makes it a delicious and satisfying meal.
