Boil Korean sweet potato noodles and set them aside to drain (see notes section). If adding broccolini, hot water blanch them for a few minutes until they turn deep green color with crunchy texture and not mushy. Rinse in cold water and set aside to drain.
In a large well-heated skillet, add 1 tbsp cooking oil, saute and reheat 2.5 cups chicken and cabbage stir-fry until they are back to room temperature. Add cooked noodles and blanched broccoli. If it feels dry to the skillet, add 1 to 2 tbsp broth a time to help stir-frying the noodles*. Taste test a small bite of the dish then decide if you want to add the “Stir-Fry Sauce”. Give the noodles, chicken, and vegetables a quick toss so the flavor is coated well over each ingredient.
Serve hot, in room temperature, or slightly chilled. Garnish with toasted sesame seeds and 1-2 tsp toasted sesame oil (optional)
