Омлет з базиліком

2. Heat a 10" nonstick pan over medium heat. Add the oil and butter. When butter foams, pour in the egg mixture. Turn heat down and cook, drawing cooked egg from sides, lifting cooked egg gently from bottom to let uncooked through. When omelet is mostly set through, 4-5 minutes, slide carefully onto a dinner plate. Place pan over the plate and invert omelet, uncooked side down, back into the pan. Finish cooking, a couple more minutes. Slide omelet off the pan onto serving plate.
