You must try stir-fried romaine lettuce! It's a fast and easy recipe, nut-free, and free of top 9 allergens. It's a perfect simple side dish to serve with foods that are rich or highly seasoned.
Wash and separate the romaine leaves, tear them in half so that the stems are about 3 inches long. Set aside to drain in a colander until ready to cook.
Preheat a large skillet or pot on medium heat for 5 minutes. Add the oil, swirl to coat, sprinkle the salt, and add the romaine leaves.
Spread the stir-fried romaine leaves and allow them to sear and cook down slightly, stir fry until half of the romaine looks translucent (1-2 minutes).
Drizzle approximately 1 teaspoon of oyster sauce or sesame oil, if using, and continue to stir-fry. The romaine is ready when most of the romaine looks translucent.
