How to Make It
Rinse the chicken and pat dry. Cut or pound the chicken breasts into 1/2-inch-thick pieces. Season with salt and pepper and set aside.
In large bowl, beat eggs and set aside. In another large bowl, mix together the panko and Parmigiano-Reggiano.
Coat the chicken in egg and then dredge it in the panko/cheese mixture. Shake off any excess and set the coated pieces aside. Repeat with the remaining chicken.
Heat 1/4 inch of oil in a large skillet over medium-high heat. After the oil is hot, add the chicken. Cook for 5 to 7 minutes, turning once, until the chicken is golden and cooked through.
To serve, top the cooked chicken with hot tomato sauce, mozzarella cheese and garnish with parsley.
