* To cook this on a gas grill, you want the burner under the skillet to be off. With a three burner gas grill, preheat grill to 450°F by adjusting the left and right burners to medium-high and leaving the middle burner off. Once grill reaches a consistent temperature, place dish over middle burner. Avoid opening the grill cover as you lose a lot of heat.
* Don't have thyme and/or sage? Use whatever fresh herbs you have.
* Aged balsamic vinegar is thicker and has a more concentrated flavor. Just a little adds great flavor. You an also use regular balsamic vinegar.
