Step 1

Cut chicken in half horizontally. Top each half with one-fourth the cheese. Wrap pancetta around cheese; tuck ends under chicken.

Step 2

In large nonstick skillet heat oil over medium-high heat. Cook chicken, cheese side up first, over medium heat for 4 to 5 minutes. Turn; cook 4 to 5 minutes, until golden brown and no pink remains in chicken. Transfer to platter; cover to keep warm.

Step 3

Remove skillet from heat. Add dates, vinegar, and water to skillet. Return to heat. Cook, uncovered, for 5 to 7 minutes, until sauce is thickened and dates are soft, stirring to scrape up browned bits.

Step 4

Spoon sauce over chicken. Sprinkle lightly with salt and pepper.
