To make the dough, place flour and salt in a large bowl and mix until well-combined.
Gradually pour in the water and stir to combine. Then, knead into a soft dough, for about 8 - 10 minutes. Cover and let it rest for 30 minutes.
Meanwhile, prepare the filling. Soak the mung bean thread noodles in hot water for 10 minutes to soften it. Drain and cut or chop into smaller pieces.
Clean chives by removing the browned part and rinse with water. Then, chop into 1cm length and transfer to a large bowl.
Mash tofu in a non-stick pan into crumbles, add a drizzle of oil, then sauté them until golden brown and season with salt.
Add cooked tofu, mung bean thread noodles into the chopped chives bowl. Then season with soy sauce, sugar, salt, a few dashes of white pepper and toasted sesame oil. Mix until all ingredients are incorporated.
To make the pockets, dust countertop with flour and divide dough into 12 equal parts.
Take one dough ball and flatten it with your palm (cover the rest with a towel). Roll the dough into a circular disc.
Place about 2 - 3 tablespoons of filling in the middle and bring the edge from one side to meet the other end and pinch seal to make a half moon shape.
To cook the pockets, heat a non-stick/cast iron pan with a drizzle of oil.
Pan-fry pockets until golden brown, for about 3 to 5 minutes, then flip and cover the pan with a lid. Continue to cook for another 3 to 5 minutes.
Remove and place pockets on a baking sheet pan and cover with a towel. This step is to give the pockets the chewy outer layer. Serve warm with sambal oelek.
