Zucchini and Feta Gratin

• 1 1/2 pounds zucchini -- 750gr 1/4" slices
• 3 ounces feta cheese
• salt and freshly ground pepper
• 2 teaspoons mint -- or 1tbsp fresh
• 4 eggs
• 1 pinch nutmeg -- grated

1. This gratin is quickly assembled, and can be eaten hot or cold. The combination of mint and feta gives it the most refreshing flavor. It can serve as a main dish or side.
2. Preheat the oven to 375°F-190°C. Oil a 2-quart gratin dish with olive oil.
3. Steam the zucchini for 5 minutes. Refresh with cold water and drain on paper towels.
   
4. Transfer to the gratin dish and toss with salt and pepper.
5. Blend together the eggs and cheese in a food processor, or in a bowl with a whisk, until fairly smooth. Add the mint and nutmeg, and a scant 1/4 teaspoon salt.
6. Pour over the zucchini. Bake 30 to 40 minutes, until set and just beginning to brown on the top. Serve hot, warm or at room temperature.
