Tiger-striped chicken

I hadn't used my griddle pan for such a long time but catching an old Nigella Bites episode and hearing her mentioning how much she liked her tiger-stripes on a great hunk of steak got me to dust it off for my chicken breast. I can see why she such a fan of the tiger-striping, it does give an ordinary (but happy) chicken breast a pleasing appetizing appearance and, very importantly, a bit of extra tastiness. And perched on top of a good little pile of creamy leeks, a perfect simple little meal.
