Hollow out a small pocket, stuff it with something tasty (sundried tomato paste, tapenade, pesto, cheese, etc), and roll it up in a slice of pancetta or parma ham and pan fry it.
Make a paste out of a decent chicken stock cube (Kallo are good) and olive oil, rub this into the skin of your chicken breast, allow to penetrate for a bit and then pan fry.
Marinade the chicken in a mixture of Rose Harissa, olive oil and lime juice and then lightly pan fry and serve with couscous.
Flatten a breast between two pieces of clingfilm, breadcrumb it (flour, beaten egg, seasoned breadcrumbs) and pan fry that for Chicken Milanese.
Hollow out a pocket, stuff that with garlic butter, close it up, breadcrumb the breast and bake in the oven for a fantastic home-made Chicken Kiev.
The possibilities are endless.
