In Tunisia, baked omelets sometimes contain fish, while in Greece and Iran, yogurt is often stirred into the mix. Baked frittatas are easy to make and hold well in the refrigerator, and they’re equally good hot, cold or at room temperature. Make one for dinner, and pack up the leftovers for lunch. Many of my favorite Tunisian omelets are baked in the oven. This one can range from mildly spicy to very spicy, depending on your taste.
02While the eggplant is in the oven, heat 1 tablespoon of the olive oil over medium heat in a large, heavy nonstick skillet, and add the onion and pepper. Cook, stirring often, until tender, 5 to 10 minutes. Add a pinch of salt, stir in the garlic and eggplant and cook for one more minute, stirring. Remove from the heat. Season to taste with salt and pepper.
03Place the remaining tablespoon of oil in a 2-quart casserole or a 9-inch cast iron skillet, brush the sides of the pan with the oil, and place in the oven. Meanwhile, in a large bowl, beat the eggs and add the parsley, cheese, salt (about 1/2 teaspoon), pepper, cinnamon and cayenne. For a spicier dish, whisk in about a teaspoon of harissa or more, to taste. Stir in the eggplant mixture.
04Remove the pan from the oven, and pour in the egg mixture. Bake 35 to 40 minutes, until lightly browned on the top and set. Allow to cool for 10 minutes or longer before serving. Serve hot or at room temperature, cut into wedges or squares.
