Heat the oven to 425°F. Slice the eggplants into 0.5-inch rounds, brush with olive oil, season with salt, and roast on two sheet pans for 20 minutes until soft and golden.
Meanwhile brown the lamb with the onion and garlic for 8 minutes, drain, then add the tomatoes, cinnamon, oregano if you have it, salt, and pepper and simmer 10 minutes.
Whisk the Greek yogurt, eggs, and half the parmesan for a quick creamy topping.
Lower the oven to 375°F. Layer half the eggplant in a 9x13 dish, then the meat sauce, then the remaining eggplant; spread the yogurt topping over and sprinkle with the rest of the parmesan.
Bake 25 to 30 minutes until set and golden, then rest 10 minutes before serving. Ground beef works fine if you can't find lamb.
