Cut off the lower end of the asparagus stalks. Cut the sticks into pieces approx. 5 cm long. Halve thick pieces lengthways. Roast the walnut halves dry in the pan until they smell aromas.
Heat a wok well and add cooking oil. Put the asparagus pieces in the hot oil and add a little salt. Fry for about 1 minute while stirring. Add Szechuan pepper, 5-spice powder, garlic, ginger, sugar, chili peppers, soy sauce and walnuts. Roast for 1 - 2 minutes. Turn it often so that the asparagus pieces are well seasoned everywhere. The asparagus should still be firm and bright green in color. He will cook a little more.
Arrange the asparagus on serving plates. Scatter the spring onions on top and decorate with coriander leaves.
Tip: The 5-spice powder can also be made from Szechuan pepper, fennel seeds, cloves, star anise and cinnamon, ground in equal parts.
