Persian Herb Frittata

Preparation

1. Step 1

   In a small bowl, soak the barberries in cold water for 20 minutes. Using a sharp knife, finely chop the parsley, cilantro, scallions and romaine lettuce; combine in a large mixing bowl.

2. Step 2

   In a medium mixing bowl, combine eggs, salt and pepper. Whisk just until frothy. Drain the barberries, making sure to discard any small stones.

3. Step 3

   Place an 11-inch skillet over medium heat. Add ¼ cup and 2 tablespoons of the olive oil, and heat until shimmering. Add the beaten eggs, barberries and walnuts to the chopped greens. Mix well, and pour into skillet, spreading it evenly. Cover the pan, and cook until set, about 10 minutes.

4. Step 4

   Uncover skillet and divide the frittata into four wedges, separating them from one another slightly so that the liquid from the frittata can evaporate. Reduce the heat to low, and cook uncovered until the underside is browned, about 40 minutes.

5. Step 5

   Turn the frittata over, one wedge at a time. Drizzle remaining 2 tablespoons olive oil inside the edge of the skillet and between each wedge. Continue to cook uncovered until the underside is browned and the frittata is compact and crisp on both sides, an additional 40 minutes. Serve hot or at room temperature, with yogurt on the side, if desired.
