Peel the carrot, halve it lengthwise and cut into thin slices. Core the bell pepper and cut into bite-sized pieces. Cut the broccoli into small florets. Clean the mushrooms and cut into six pieces. Cut tofu and seitan into bite-sized pieces.

Peel and finely dice the ginger. Peel, halve and finely slice the garlic. Fry both in a large frying pan with sesame oil on relatively high heat for about 20 seconds. Then add the remaining vegetables. Stir-fry everything for about 1 minute. Add the sauce.

Add the udon noodles and the tofu/seitan to the pan. The noodles will seperate by themselves in the hot sauce. Just turn them from time to time, so they all get in touch with the sauce. After 2-3 minutes everything should be done.

Serve the udon noodles immediately sprinkled with sesame seeds.
