Cut each chicken breast in half lengthwise, ending up with 4 pieces. Pound chicken to ½ inch thick.
Season chicken breasts on both sides with salt and pepper.
Into 3 separate shallow dishes, place flour, beaten egg, and Panko crumbs.
Coat both sides of each chicken breast in flour, shaking off any excess; then dip into egg, and then press into Panko crumbs until well coated on both sides.*
To a large skillet, add oil to reach about ¼ inch deep. Heat oil over medium high heat until it reaches 375F. Place chicken in the hot oil, and fry 3-4 minutes per side, or until golden brown and chicken is cooked through (internal temperature of 165F). Remove from oil and drain on paper towels. Repeat to use remaining chicken.
Serve with tonkatsu sauce or your sauce of choice.
