Heat a wok or thick bottom kadhai / pan, add oil. Now add finely chopped garlic, ginger, green chilli and spring onions. Saute well until the ingredients have no raw smell.
Now add the chopped mixed vegetables.
Sprinkle salt to taste and black pepper powder. Saute for a couple of minutes until the vegetables have cooked slightly.
Add the condiments - soy sauce, sriracha sauce, tomato ketchup and green chilli sauce. The sauces should coat the vegetables well.
Now add water, allow it to reach a boil. (You can use stock instead of water)
In the meanwhile, make a slurry using 2 tsps of cornflour with 1/2 cup of water. Mix well and add it to the gravy.
The gravy would thicken. Check for seasoning and add extra if required. Ensure the flame is on medium heat.
Once the gravy has thickened. Switch off the flame, add finely chopped spring onion greens and serve with fried rice or noodles.
