Quick Answer
For a practical Cantonese vegetable stir-fry, start with bok choy rather than combining vegetables that need different cooking times. The goal is tender stems, intact leaves and a little glossy liquid, not a thick sauce blanket.
Basic Facts
- Four side portions; roughly 5 minutes at the stove after washing; bok choy, ginger and garlic; wok or large skillet.
Ingredients
Use 680-790 g bok choy, 3 tbsp neutral oil, one slice ginger, four garlic cloves, half to three-quarters tsp salt and a pinch of white pepper. Optional: half a tsp sesame oil. Mix 1.5 tsp cornstarch with 2 tbsp water separately.

Wash the stem bases thoroughly
Halve small heads or separate large stems. Agitate in water, lift the vegetables out and repeat until no grit remains. Drain well; water clinging to the leaves becomes part of the liquid in the wok.
Let the vegetables set the heat
Warm oil and ginger over low heat. Add garlic briefly without browning, then add bok choy and raise the heat. Toss so leaves and stems contact the pan; cover briefly if needed to soften thicker stems. Season when the greens begin to wilt.

Add slurry only when there is liquid
Stir the slurry again. Add it gradually to the cooking liquid and toss until a light coating forms. Stop before the greens become limp. Use only as much slurry as the liquid needs and plate at once.
Quick reference
In a small skillet, divide the washed greens into batches and split the seasonings accordingly. A crowded pan is difficult to toss safely. If garlic starts darkening before vegetables go in, lower the heat and replace burnt garlic rather than covering its taste with sauce.

Frequently Asked Questions
Can I add oyster sauce to this vegetable side?
Yes, but reduce the salt and check shellfish allergens. Mushroom-based sauce is an alternative, not proof that every bottled product is vegetarian.
Should I use this same timing for carrots and broccoli?
No. This example is for bok choy. Separate dense vegetables or use a recipe with blanching instructions for them.
