Step 1

Preheat broiler to high.

Step 2

Mix 2 tablespoons oil, artichoke hearts, salami, pepperoncini, vinegar and oregano in a medium bowl.

Step 3

Heat the remaining 1 tablespoon oil in a large ovenproof skillet over medium-high heat. Sprinkle chicken with pepper and add to the pan. Cook until starting to brown, about 3 minutes. Turn the chicken over and top each piece with the artichoke mixture and cheese. Transfer the pan to the oven and broil the chicken until the cheese is browned and an instant-read thermometer inserted in the thickest part of the chicken registers 165 degrees F, 3 to 4 minutes more. Serve the chicken with any pan drippings and oregano, if desired.
