Poulet Grillé à la Diable In French cooking, any meat or poultry seasoned with mustard and hot pepper and then coated with breadcrumbs is called à la diable, since the devil, or diable, is associated with anything hot and fiery. Cafés and bistros all over Paris offer versions of this classic. I like to make mine with a combination of sharp Dijon and coarse-grain Dijon mustard, and with a good hit of spice, usually what the French call piments langues d'oiseaux, or bird's-tongue peppers. This is a great picnic dish as well, and I often make it for our lunch when we take the train to Provence. When we eat at home, I serve this chicken with steamed rice or sautéed potatoes and a green salad.
