Cut the zucchini into coins.
Remove the florets from the cauliflower and broccoli. Cut the stems into small pieces.
Leave the baby corn whole.
Add the oil to large pan or wok. Wok would be best if you have one.
Once the oil is shimmering, add all the vegetables.
Stir every so often. Cook for 5 to 7 minutes until all the vegetables are tender. Remove from the heat.
Mix together all the ingredients of the sauce and drizzle it over all the veggies. Serve as a side with or without rice. You can add in some chicken to make it a full meal.
