Potato and Zucchini Frittata
1 small russet potato, peeled and cut into 1/2-inch cubes
4 large eggs
2 egg whites
2 tablespoons coarsely chopped fresh cilantro leaves
3/4 teaspoon salt
1/4 teaspoon hot sauce
1 tablespoon olive oil
1 garlic clove, minced
1 small onion, finely chopped
1 small zucchini (about 6 ounces), grated and squeezed dry in clean kitchen towel
1/2 cup queso fresco (2 ounces)
2 strips cooked crumbled turkey bacon, optional
Bring the potatoes with enough cold water to cover to a boil in a small saucepan. Cook, over medium-high heat, until the potatoes are tender, 6 to 8 minutes; drain and pat dry.
Whisk together the eggs, egg whites, cilantro, salt, and hot sauce in a large bowl.
Preheat the oven broiler to medium-high.
Heat the oil in a medium (10-inch) ovenproof nonstick skillet over medium-high heat. Add the garlic and onion and cook, stirring occasionally, until the onion is translucent, 2 minutes. Add zucchini and cook until tender, about 6 minutes more. Add the cooked potatoes and cook, stirring occasionally, until the potatoes begin to brown slightly, about 4 minutes more.
Evenly pour the egg mixture over the vegetable mixture. Cook, over medium heat, tilting the pan and lifting the edges with a rubber spatula to let the uncooked egg flow underneath. Sprinkle with the cheese and the bacon, if using.
Broil, 5 to 7 inches from the heat, until the eggs puff and are just set and the cheese is golden brown, about 5 minutes.
Remove carefully to a plate, or serve in wedges directly from the skillet.
