Heat a non-stick skillet on medium high heat, add peanut oil. When oil is hot, add garlic and stir until fragrant. Add carrot and keep stirring until carrot is half cooked, around 40 seconds. Add water chestnuts and snow peas, keep stir frying for around 2 minutes. Add salt and stir for another 1 minute, until all vegetables are cooked through but still crispy.

Place all vegetables on a plate and serve while warm.
