📖 Instructions

1. Let's prep the Eggplant: Slice the eggplant into 1/4-inch thick rounds. I like to use a mandoline for even slices, but a knife works just fine too! Place the slices in a colander, sprinkle with salt, and let them sit for 30 minutes. This helps draw out excess moisture, so your sandwich isn't soggy. Trust me, this step is IMPORTANT!
2. Now, the Lamb Sauce: In a skillet over medium heat, brown the ground lamb. Drain off any excess grease. Add the diced onion and garlic, cook until softened, about 5 minutes. Stir in the tomato paste, crushed tomatoes, cinnamon, and oregano. Season with salt and pepper to taste. Reduce heat and simmer for 15 minutes, stirring occasionally. The sauce should thicken slightly.
3. Lets Roast Eggplant: Preheat your oven to 400°F (200°C). Rinse the eggplant slices and pat them dry. Toss them with olive oil, salt, and pepper. Spread them in a single layer on a baking sheet. Roast for 20-25 minutes, flipping halfway through, until tender and lightly browned. Keep an eye on them – you want them tender, not burnt!
4. For the Béchamel Sauce: In a saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, until it forms a smooth paste (a roux). Gradually whisk in the milk, making sure to break up any lumps. Continue whisking until the sauce thickens, about 5-7 minutes. Remove from heat and stir in the nutmeg, Gruyère cheese, and Parmesan cheese. Season with salt and pepper to taste. This is where the magic happens, so don't rush it!
5. Assemble Your Sandwich: Butter one side of each bread slice. Place two slices of bread, butter-side down, in a large skillet over medium heat. Layer with half of the roasted eggplant, half of the lamb sauce, and half of the béchamel sauce. Top with the remaining eggplant, lamb sauce, and béchamel sauce. Place the remaining bread slices on top, butter-side up.
6. Grill It!: Cook for 3-4 minutes per side, or until the bread is golden brown and the cheese is melted and bubbly. You might need to press down on the sandwich with a spatula to ensure even cooking. Be patient – a perfectly grilled sandwich is worth the wait!
7. Time to Serve: Remove from skillet, let cool for a minute, slice in half, and serve immediately. Enjoy every single delicious bite! (Maybe with a side of Greek salad for extra credit? Just sayin'.)
