Boil water in a pan. Break off asparagus' stems and discard them. Put asparagus in the boiling water along with snow peas, green beans, baby corn and the broccoli. Let it cook for 4 minutes, then drain and set aside.

Wipe the mushrooms with a wet kitchen towel (so that they don't absorb water), cut them to your liking and fry for about 3 minutes on each side until golden. Sprinkle with black pepper just before turning, and add a bit more oil if needed. Set aside.

Cut the tofu into long stripes (think of thick french fries). Make sure there is a bit of oil remaining in the pan, and fry the tofu stripes on one side for 1 minute (just to make it crispy on that side). Turn it to another side for 1 minute.

Now, sprinkle the tofu with black pepper and pour about 2 tbsp of teriyaki sauce on top, so that the tofu absorbs some flavour before the sides get crispy. Fry for a minute and a half on each of the two remaining sides.

Throw everything (boiled vegetables and fried mushrooms, onions and bell pepper) into the frying pan. Pour 3 tbsp of teriyaki sauce and 3 tbsp of sweet chilli sauce on top (or change the amount based on your taste), and generously sprinkle with black pepper. Stir and move everything around for 5 minutes.
