Potato and Leek Frittata

1 1/2 pounds boiling potatoes

3 cups thinly sliced white and pale green part of leek, washed well and drained

2 tablespoons unsalted butter

12 large eggs

1 cup freshly grated Parmesan

1 cup coarsely grated Gruyere

2 tablespoons snipped fresh chives

2 tablespoons minced fresh parsley leaves

2 tablespoons olive oil

Cook the potatoes in water for 20 to 25 minutes until they are tender. Drain, cool, peel and cut into thin slices. In a 12-inch non-stick skillet cook the leek in the butter over moderately low heat, stirring, for 12 to 15 minutes, or until it is very soft, and add salt and pepper to taste. In a large bowl whisk together the eggs, add 1/2 cup of the Parmesan, 1/2 cup of Gruyere, the chives, the parsley, and salt and pepper to taste, and whisk the mixture until it is combined well. Stir in the leek and the potatoes. In the skillet, cleaned, heat the oil over moderate heat until it is hot but not smoking, pour in the egg mixture, distributing the potatoes evenly, and cook the frittata, without stirring, for 14 to 16 minutes, or until the edge is set but the center is still soft. Sprinkle the remaining 1/2 cup Parmesan and the remaining 1/2 cup Gruyere over the top. If the skillet handle is plastic, wrap it in a double thickness of foil. Broil the frittata under a preheated broiler about 4 inches from the heat for 4 to 5 minutes, or until the cheese is bubbling and golden. Let the frittata cool in the skillet for 5 minutes, run a thin knife around the edge, and slide the frittata onto a serving plate. Cut the frittata into wedges and serve it warm or at room temperature. Serves 6.

CHERRY TOMATO, BACON, AND BASIL SALAD

5 cups cherry tomatoes, halved

6 slices of lean bacon, cooked until crisp and crumbled

1/3 cup finely chopped fresh basil leaves, or to taste

2 tablespoons red-wine vinegar

4 tablespoons olive oil

In a bowl toss together the tomatoes, the bacon, and the chopped basil until the mixture is combined well. In a small bowl whisk together the vinegar and salt and pepper to taste, add the oil in a stream whisking, and whisk the dressing until it is emulsified. Pour the dressing over the tomato mixture, toss the salad lightly until it is coated well with the dressing, and garnish it with basil sprigs. Serves 6.
