Preparation:

1. Cut the vegetables into bite-size pieces. Mix them in a bowl and put them into boiling water for a few minutes to blanch. Drain and set aside.
2. Heat the oil in a frying pan, and saute the garlic. Then, add the vegetables and stir-fry for approximately 2-3 minutes using high heat. Quickly fry to ensure the right texture of the vegetable.
3. Add oyster sauce, white soya sauce and sugar to add flavor. Sprinkle with peppercorn. Fry for 1 minute.

Note : Hard-textured vegetables like cauliflower, carrot and broccoli should be pre-boiled to minimise the frying time.
