Prepare Yeast Mixture: Mix boiling water with cold water to make it lukewarm. Dissolve sugar and active dry yeast in the lukewarm water. Add salt and 1 tablespoon of vegetable oil, then mix well.
Make Dough: Add all-purpose flour to the yeast mixture and mix until a dough forms. Let it sit until it doubles in size, about 1 hour.
Cook Noodles: Boil sweet potato starch noodles for about 6 minutes until soft and translucent. Drain and chop into small pieces.
Stir-fry Noodles: Stir-fry the noodles with 1 tablespoon sugar, 2 tablespoons soy sauce, and 1/4 teaspoon ground black pepper until dark brown and shiny. Add 1 teaspoon sesame oil at the end.
Prepare Vegetables: Chop carrot, onion, and Asian chives into small pieces and mix with the stir-fried noodles.
Form and Cook Pancakes: Divide the dough into portions. Flatten each portion, add the noodle and vegetable mixture in the center, seal, and shape into a pancake. Deep fry in vegetable oil at 350°F until golden brown and crispy or pan-fry as a lower-calorie option.
