Chicken Keiv in the most simple terms is a chicken breast, sliced into to make a pocket, in the pocket you put beautiful garlic butter, with herbs if you like, then egged and breaded and then baked ( sometimes first fried ) . A World classic.... with many, many variations.

p.s. I love, love love Mad Men.... I learned so much, like in the U.S.A. you had microwaves 45 years before us in the U.K........45 years... uh.
