Heat a large sauté pan over medium heat. Add the olive oil and the butter and swirl the pan until it’s coated and the butter mixture is hot and bubbly. Add the chicken, smooth side down. Chicken should sizzle a bit when it hits the oil. Cook for 4-5 minutes or until underside is a nice golden color. Turn and cook for another 1 minute. (The chicken will not be done at this point, but will finish cooking in the sauce.) Remove chicken from the pan to a clean plate.
