Step 1

Place the chicken cutlets flat on the work surface. Sprinkle the chicken with salt and pepper. Lay 1 slice of prosciutto atop each chicken cutlet.

Step 2

Squeeze the frozen spinach to remove the excess water. Season the spinach with salt and pepper. In a small bowl, toss the spinach with 1 tablespoon of oil to coat.

Step 3

Arrange an even, thin layer of spinach atop the prosciutto slices. Sprinkle the Parmesan evenly over each. Beginning at the short tapered end, roll up each chicken cutlet as for a jellyroll. Secure with a toothpick.

Step 4

Heat the remaining 2 tablespoons of oil in a heavy large skillet over high heat. Add the chicken and cook just until golden brown, about 2 minutes per side. Add the chicken broth and lemon juice, and scrape the browned bits off the bottom of the pan with a wooden spoon. Bring the liquid to a boil. Reduce the heat to medium. Cover and simmer until the chicken is just cooked through, about 8 to 10 minutes. Transfer the chicken to a platter. Simmer the cooking liquid over high heat until it is reduced to about 2/3 cup, about 5 minutes. Season the cooking liquid with salt and pepper, to taste. Remove toothpicks from the chicken. Drizzle the reduced cooking liquid over the chicken and serve immediately.
