- 6 small eggplants - 1 1/2 teaspoons salt - 1/8 teaspoon freshly ground black pepper - 1 1/2 cups tomato sauce - 1 1/2 tablespoons medium-chopped fresh flat-leaf parsley - 1 1/2 tablespoons unsalted butter - 4 1/2 tablespoons all-purpose flour - 1 1/2 cups skim milk - 1/8 teaspoon grated nutmeg - 3 tablespoons freshly grated Parmesan cheese - Olive-oil cooking spray

1. Heat oven to 450 degrees F. Bake eggplants until slightly softened, about 15 minutes. Transfer eggplants to a clean surface. Slice off 1/4 of each eggplant lengthwise, and reserve the pieces. Hollow out eggplants, leaving about 1/4 inch of flesh attached to the skin. Reserve the flesh. Cut removed pieces and flesh of the eggplants into 1/4-inch dice; set aside.

2. Spray a nonstick skillet with olive-oil spray, and place over medium heat. Stir in the diced eggplant, 1 1/4 teaspoons salt, and pepper. Cover, and cook the eggplant until tender, 15 to 20 minutes. Stir in tomato sauce and parsley, and cook 3 to 4 minutes. Fill the reserved hollowed eggplants with eggplant filling brimming over the top slightly, and place in a baking pan large enough to comfortably hold the eggplants. Bake for 10 minutes.

3. Meanwhile, make the balsamella sauce: Melt butter in a small saucepan over medium-low heat. Whisk in flour until all the butter has been absorbed, and cook 2 minutes. Slowly pour in 1/4 cup milk, while briskly whisking. Briskly whisk in the remaining 1 1/4 cups milk, 1/4 cup at a time, until all the milk has been added and the sauce is smooth and creamy. Stir in the remaining 1/4 teaspoon salt and nutmeg. Cook until the sauce has thickened to the consistency of pancake batter, 4 to 5 minutes.

4. Spoon about 2 tablespoons balsamella sauce over the top of each filled eggplant, and sprinkle tops with Parmesan. Bake until tops are golden and eggplants are heated through, about 20 minutes.
