• 1 can (400g) canned chopped tomatoes, drained

• 2 tablespoons Worcestershire sauce

Cheese sauce

• 6 tablespoons unsalted butter

• 5 cups whole milk, room temperature
• A pinch of freshly grated nutmeg
• 1.5 cups grated kefalotyri cheese or
  0.5 cup grated Parmesan mixed with 1 cup crumbled feta
• 2 large eggs + 3 yolks

Preparation:

1. Preheat oven to 230°C (430°F). Trim the eggplants and slice lengthwise into 1-cm-thick slices. Arrange on two large foil-lined baking sheets; brush generously with 1/2 cup olive oil and sprinkle with salt and black pepper. Bake until tender, about 30 minutes.
2. In a heavy-bottomed Dutch oven or saucepan, heat the remaining 2 tablespoons olive oil over medium heat; add the Swiss chard and season with salt and pepper. Cook, stirring, until the greens are wilted, about 4 minutes. Transfer to a colander and cool; squeeze out any excess water and set aside.
3. Wipe the pan dry, add the butter, and melt over medium heat. Add the onion and cook until golden brown, about 4 minutes. Add the garlic and cook for another minute. Add the ground beef, breaking it up, along with the oregano, cinnamon, nutmeg, 2 teaspoons of salt, and black pepper to taste; cook until browned, about 2 minutes.
4. Add the wine and cook, stirring, until the meat is cooked through but still slightly pink, another 1 minute. Add the diced tomatoes, tomato paste, Worcestershire sauce, and bay leaf, bring to a simmer, cover, and simmer for 30 minutes.
5. Meanwhile, lightly grease a 9 x 13-inch baking dish with olive oil and sprinkle with breadcrumbsPlace the potato slices in a baking dish, pat dry with paper towels, and season with salt and black pepper.
6. While the meat sauce is simmering, prepare the cheese sauce..
   
   Melt the butter over medium heat. Add the flour, stirring gently until a soft paste forms. Remove from heat, stir in the milk, nutmeg, and 2 teaspoons of salt. Return to the heat and bring to a boil, whisking constantly. Remove from heat again, stir in 1 cup of cheese, and let cool slightly, then whisk in the eggs and yolks.
7. Reduce the oven temperature to 350°F (175°C). Arrange half the eggplant on top of the potatoes. Top with half the meat sauce, then half the chard. Repeat with the remaining eggplant, meat sauce, and chard. Drizzle with the cheese sauce and sprinkle with the remaining 1/2 cup kefalotyri cheese. Bake the moussaka, uncovered, until the sauce is set and lightly browned on top, about 1 hour. Let rest for 20 minutes before serving.
