Take another cooking pan and add oil.
Let the oil heat. Then put the finely chopped ginger and garlic.
Sauté them for about half a minute and then add the onions, chopped green chilis, and bell peppers.
Stir them all for a minute. Add 1 tbsp spring onions to it.
Sauté them for 1 more minute. We don’t want to overcook the veggies or else they will get mushy.
While the veggies are getting fried, take a medium-sized bowl and put in the tomato ketchup, soy sauce, red chili sauce, green chili sauce, Kashmiri red chili powder, vinegar, corn starch, and water (½ cup).
Mix all these into a slurry and pour them into the kadhai or pan.
Combine all the ingredients. Add another 1 cup of water (you can add more or less if needed).
Add salt and sugar to taste.
Give it a taste test. Add if anything is needed.
