Dry the chicken cubes with paper towels and toss them with the flour, salt, and pepper in a bowl. Trust me, don’t be tempted to ad more flour, the amount mentioned is perfect. Heat the oil in a 12-inch skillet over high heat until very hot but not smoking, add the cubed chicken, and cook in one layer, for about 4-5 minutes, this will develop a lovely crust. Turn pieces of chicken and continue cooking for 3-5 more minutes.
Meanwhile, combine the garlic and parsley in a small bowl. Add the butter and the parsley mixture to the skillet and saute for 1 minute longer, shaking the skillet occasionally to coat the chicken. Use a spoon to remove the chicken to a plate, leaving brown bits, extra parsley and garlic in the pan.
