Butterfly the chicken breasts and dip them in the seasoned flour, eggs, and panko, shaking off any excess as you go.
Fry them in oil until crisp and cooked through then set aside somewhere warm.
Lay the tortillas on a baking tray to make a rectangle. Scatter with grated Emmental. Place the fried chicken pieces on top and cover with ham and then the Emmental.
Place more tortillas on top and cover with a layer of greaseproof paper and another baking tray. Bake for around 20 minutes until the tortillas are crispy.
