Japanese Stirfried Buckwheat Noodles

1 lb dry buckwheat noodles (soba)
4-6 cups chopped veggies of your choice
(broccoli, mushrooms, green onions, celery, snow peas, garlic, sliced onions,
cauliflower, whatever you have on hand)
sesame oil

Tonkatsu Sauce:
1 cup ketchup
4 tbsp soy sauce
1 tsp (or more) wasabi powder

Boil the soba noodles according to package directions. Drain and set aside. In a large skillet or wok, heat the sesame oil for a minute, then toss in all the veggies and fry for 3-5 minutes, until they turn bright colours but are tender-crisp. Add the soba noodles and tonkatsu sauce and stir fry over high heat for a few minutes more until everything is mixed together nicely. Serve piping hot.

Serves 4.
