These Sesame Sweet Potato Glass Noodles bring bright flavors and the perfect balance of chewy, tender noodles with a sweet and nutty sesame sauce. Whenever warmer weather hits, this is my go-to dish for lunches or light dinners because it feels fresh yet so satisfying.
My love for sweet potato noodles started after a friend brought japchae to a picnic. After that I found ways to make this at home for my family and they never leave leftovers behind.
