Defrost the spring roll dough. Soak mushrooms in cold water. Put glass noodles in boiling water. Remove the pan from the heat and let the noodles stand for 3-4 minutes. Drain and let drain.
For the filling, peel the onions and cut into strips. Pour mushrooms into a sieve, drain well and chop coarsely. Drain bamboo and cut into fine strips. Roughly chop the glass noodles. Wash coriander, shake dry and chop except for a little bit for garnishing.
Season prepared vegetables and glass noodles with soy sauce, salt, pepper, ginger, turmeric and coriander and mix thoroughly. Place 4 spring roll leaves side by side on the work surface. Pour 1-2 tbsp. of filling into the lower left corner, leaving a 4 cm margin at the top.
Brush the edges with water. Whip the tip over the filling. Roll over corners from both sides towards the middle and roll up to a firm roll. Do the same with the remaining pastry sheets. Heat oil in a pot and bake the spring rolls in portions in hot fat for 4-6 minutes until golden brown.
Arrange the spring rolls. Serve with Asian chili sauce. Garnish with coriander.
