Set the Instant Pot in the saute mode and when it is hot, add 1 tbsp of sesame oil. Now add the chopped green onions (reserve the green part for garnishing), garlic cloves, green chili, and ginger. Saute for 30 to 45 seconds or until the garlic browns lightly.
Next, add the veggies. I used 2 cups of finely chopped mixed vegetables - green bell peppers, carrots, mushrooms, green beans, and cabbage. Add the salt and ground pepper and mix the veggies.
Now add all the sauces - dark soy sauce, vinegar, and green chili sauce. Mix them all.
Add all the liquids now - 2 cups of vegetable broth and 2 cups of water. Mix thoroughly. Press the cancel button, and close the Instant Pot. Make sure the sealing ring is in place and set the vent to the sealing position. Cook the soup at high-pressure manual/pressure cook mode for 2 minutes, and after the cooking is done, release the pressure after 10 to 12 minutes.
Carefully open the Instant Pot lid once the pressure has subsided. Set the Instant Pot in saute mode again. Mix 2 tbsps of cornflour with 2 tbsp of water and make a slurry. Add this to the soup and mix it well. Add the cilantro and the green part of the green onions and let it simmer for 7 to 10 minutes.
Turn off the Instant Pot and let it rest for a few minutes. Add the fried noodles before serving and serve hot.
Instead of sesame oil, you can use peanut oil or any neutral oil.
You can use veggies of your choice, and there is no set measure. But I don't add more than 2 tbsp of chopped bell peppers as it overpowers the flavor. It's a taste preference. Adjust accordingly.
Since we love spicy soup, I added green chili, ground pepper, and green chili sauce. So please adjust the spice measure as per your taste. You can ignore the green chili if needed. I have tried this soup with red chili sauce.
Make sure to add the fried noodles just before serving. If not, it will become soggy.
As we include ingredients high in sodium content, add salt as required or a little less. If needed, add later.
Adjust the cornflour slurry as per your consistency preference. If you want a thinner consistency, reduce the cornflour.
