Rather than eliminating yolks altogether, we used fewer—to reduce fat and to avoid the rubbery texture that can be obtained by using only egg whites.

　　

Ingredients

serves 4

　　2 tablespoons olive oil

　　1 large onion, halved and thinly sliced

　　1 baking potato (8 ounces), peeled and thinly sliced

　　1/2 teaspoon dried rosemary, crumbled

　　Coarse salt and fresh ground pepper

　　5 large eggs

　　5 large egg whites

　　1/2 cup whole flat-leaf parsley leaves

　　

Bell pepper sauté

2 bell peppers, red, yellow, or both

　　1 tablespoon olive oil

　　1/2 small red onion, diced

　　Coarse salt and fresh ground pepper

　　(serves 4)

　　

Step 1

In a medium (10-inch) nonstick broiler-proof skillet, heat 1 tablespoon of the oil over medium heat. Add the onion, potato, and rosemary; season with salt and pepper, and toss to combine.

　　

Step 2

Cover the skillet, and cook for 10 minutes; uncover. Cook, tossing the mixture occasionally, until the onion and potato are tender, about 5 minutes.

　　

Step 3

Meanwhile, in a medium bowl, whisk together the eggs, egg whites, parsley leaves, 3/4 teaspoon salt, and 1/4 teaspoon pepper.

　　

Step 4

Heat the broiler with a rack set 4 inches from the heat. Add the remaining tablespoon oil to the vegetables in the skillet. Pour the egg mixture into the skillet.

　　

Step 5

Cook on the stove, over low heat, lifting the mixture a few times around the edges with a spatula to let egg flow underneath. Continue cooking until the frittata is almost set in the center, about 10 minutes.

　　

Step 6

Place the skillet under the broiler; broil until the frittata is set and the top is lightly golden, about 3 minutes. Run a clean spatula around the edges to loosen, then slide the frittata out onto a serving plate, and cut into wedges.

　　

Bell pepper sauté

Step 7

Remove the seeds and ribs from the peppers; cut lengthwise into strips and halve crosswise. Heat the oil in a large nonstick skillet over medium heat. Add the peppers and onion; season with salt and pepper. Cook, stirring occasionally, until the peppers are just tender, about 10 minutes.
