Season the chicken with salt and black pepper as desired.
Set a large skillet over medium-high heat. Add the olive oil and allow to heat through for 30 seconds.
Then, place the chicken breasts into the skillet without overlapping.
Brown the chicken completely on one side, about 2 to 3 minutes, prior to flipping the chicken.
Once the chicken is turned, add the chicken stock to the skillet and cook until the chicken is done. Preheat the oven broiler.
Spoon the barbecue sauce over the chicken and top each chicken breast with a slice of cheese.
Place the skillet under the broiler until the cheese has melted.
Top each chicken breast with diced tomatoes, sliced green onions, and crumbled bacon prior to serving.

Or, 3 boneless, skinless chicken breasts cut evenly through the thickness to make two filets
Since taking these photos I have purchased this Lodge cast iron skillet. I love it more than my others because of the dual handles. Sometimes the skillet gets so heavy when it's full, the one-handled skillets hurt my wrists. But this one with two handles doesn't. (Just wanted to let you know. 💖) It will make a great gift for anyone that enjoys cooking.
