Take chicken breasts and pound them until they're about 1-inch thick, then cut them into 4-ounce pieces.

In a bowl, whisk together balsamic vinegar, chicken broth, honey, garlic, rosemary, salt, and pepper. Set aside ½ cup of the mixture and pour what's left—about ¼ cup—into a large ziplock bag. Add the chicken to the bag.
03 -
Let the chicken marinate for 15 to 30 minutes.
04 -
Heat up a big cast-iron skillet over medium-high heat. Pour in the olive oil, and let the extra marinade drip off the chicken before putting it in the skillet. Each side should cook for 3-4 minutes or until it's done and hits 165°F inside. Use a meat thermometer to double-check.
05 -
In a separate, small skillet or saucepan, take the leftover balsamic marinade and bring it to a boil. Keep it boiling for about a minute, then turn down the heat to a gentle simmer.
06 -
Keep the balsamic mixture on a gentle simmer for 10 minutes, or until it thickens up and turns into a sticky glaze.
07 -
Plate the chicken and pour the glaze over top. Enjoy every bite!
