Dry off chicken pieces really well so a good sear can be achieved.
Season dry chicken with the salt and pepper divided equally.
Heat pan to medium heat and add 1 tablespoon of olive oil. Add seasoned chicken to the pan in 2 batches to avoid crowding. Cook approximately 2-3 minutes per side. After all the chicken is cooked set aside and lightly cover with foil to keep warm.
Turn heat to medium-low and to the same pan add 1 tablespoon of olive oil and garlic. Saute until lightly golden (about 2 minutes). Then, add tomatoes to the pan and saute for 1-2 minutes more.
Add vinegar, water, and capers to the pan and turn heat to high. Scrape the pan with a wooden spoon to remove flavorful bits. Bring to boil for 2 minutes to make the sauce.
Turn heat to low and add the cooked chicken back to the pan to combine all ingredients. Cook the chicken for 2 minutes or until warmed through.
Turn off the heat and add the parsley. Stir together. Taste test and adjust salt and pepper if required. Add a nice drizzle of extra virgin olive oil if desired. Enjoy!
