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 375°F. 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 165°F). Remove from oil and drain on paper towels. Repeat to use remaining chicken.
Serve with tonkatsu sauce or your sauce of choice.
