Thoroughly rinse water spinach in water and transfer to a colander to let the excess water drain. Heat the vegetable oil in a pan over high heat. Add garlic and fry about 1 minute, stirring constantly. Add water spinach and continue flipping and turning the spinach to saute it through, about 3 minutes. Don’t overcook it, just enough to wilt the leaves and bring out the vibrant green color. Season with salt to taste. Serve hot as a main dish or side dish. Enjoy your meal!!!
