Combine the dry ingredients in a big bowl. Make a small hollow in the center, pour in the soy milk and oil, and stir as you go. Keep mixing till a smooth dough appears. Form it into a ball, toss it back in the bowl, use a damp towel to cover, and leave it for at least 2 hours so it can rise.

Pour boiling water over vermicelli noodles, letting them soak about 7-8 minutes. Drain, then chop the noodles into small, half-inch bits. Put some neutral oil in a pan, heat it up, and stir-fry the cabbage, carrot, and scallions for 4-5 minutes on medium-high heat until soft. Then, toss in the chopped noodles along with soy sauce, sesame oil, and salt. Cook for a couple more minutes, then transfer it into a strainer so any extra liquid can drip out. Let the filling cool down.

Use your fingers to punch a hole in the middle of the dough. Pull it into a ring shape and cut it into 12-16 pieces. Roll each piece into a small ball, flatten it with a rolling pin, and make circles about 3-5 inches wide, depending on your preferred size. Sprinkle flour between each layer if you're stacking them up and cover with a dry towel if you're setting them aside for more than half an hour.

Spoon 2-3 tablespoons of the filling onto the center of each dough wrapper. Fold and pinch the edges together to seal the bun. Flatten the tops slightly, place them on a tray, and cover with a towel to keep them from drying out.

Pour 1 tbsp oil per 4 buns into a pan. Place buns in the pan, seam-side down, and cook them on medium heat for 4-5 minutes until the bottoms are golden. Flip them over to brown the other side. Add 1 tbsp of water per bun into the pan, cover, and let them steam for 5-6 minutes until all the water has evaporated. Repeat this for any remaining buns.

Put cooked buns in an airtight container and store in the fridge for up to 5 days. Reheat them on a pan with a splash of water, or use the microwave or oven. If freezing, lay them in a single layer on a tray, freeze for 5-6 hours until solid, then transfer to a storage bag.
