Greeks often add yogurt to their omelets, which contributes calcium, protein and bacteria long believed to help digestion. Yogurt also gives the omelet a light, fluffy texture. Make this with winter squash in winter and with zucchini in summer to add a great texture to the eggs.
2 tablespoons extra virgin olive oil
1 leek, white and light green parts, cleaned and chopped
2 garlic cloves, minced
3/4 pound winter squash or zucchini, cut in 1/4- to 1/3-inch dice
Salt and freshly ground pepper to taste
1/4 cup chopped fresh dill
2 tablespoons chopped fresh mint
8 organic eggs
1/2 cup drained yogurt or thick Greek-style yogurt
1/4 cup freshly grated Parmesan cheese
1. Preheat the oven to 350 degrees.
2. Heat 1 tablespoon of the oil over medium heat in a large, heavy skillet. Add the leek and cook, stirring, until tender, about three minutes. Add the garlic, stir together until fragrant, about 30 seconds, and add the squash. Cook, stirring, until tender, 10 to 12 minutes for winter squash, about 8 minutes for zucchini. Season to taste with salt and pepper. Stir in the dill and the mint. Remove from the heat.
3. Place the remaining tablespoon of oil in a 2-quart casserole or in a 9-inch cast iron skillet, brush the sides of the pan with the oil and place in the oven. Meanwhile, whisk the eggs in a large bowl. Season with salt and freshly ground pepper to taste. Whisk in the yogurt and the Parmesan. Stir in the squash or zucchini mixture.
4. Remove the baking dish from the oven and scrape in the egg mixture. Place in the oven, and bake 30 minutes or until puffed and lightly colored. Allow to cool for at least 10 minutes before serving. Serve hot, warm or at room temperature.
Yield: Serves six to eight.
Advance preparation: The squash can be prepared through step 2 as far as a day ahead.
