Rinse and dry romaine. Cut off end and Sprinkle pan with oil of your choosing. I like Grape seed Oil as it is best for medium heat. Olive oil will work fine. I let it sit for 5 minutes on medium heat and turn it. It will wilt some on the edges of the leaves.
Once it is done on all sides, about 10 minutes, drizzle with oil and sprinkle lime juice. Salt and pepper and it's done. Simple but so nice with a warm touch to a salad, nice for colder nights.
Pair with Seasoned chicken breast and potato's. Great healthy meal.
