Turn on the SAUTE mode on your Instant Pot and wait till the display shows “hot.”
Now add half of the cooking oil and sauté the green veggies (broccoli and beans) until lightly brown. Set aside.
Add rest of the cooking oil and add in minced ginger and garlic and saute for few seconds.
Then add all the other veggies (green onion white parts, carrot, and mushrooms), salt and black pepper and give a good stir.
Stir and saute for 1 minute till veggies start to sweat. Do not cook till the veggies are mushy.
Place noodles over the sautéed veggies, add water or veggie broth, and add all sauces. Alternatively, mix the sauces in water and add it over the noodles. Try to push the noodles in to the liquid.
Now close the instant pot lid, and turn valve from the VENTING to the SEALING position. Set the instant pot to manual with cooking time set for 4 minutes.
After the IP beeps, quick release the pressure and open the pot. Mix in the sautéed green veggies and tofu if using, and give a good stir.
Add smoked sesame oil and use a fork to separate the noodles sauce with the tongs.
If you see some water or sauce in the pot, it’s totally alright. The noodles absorb the sauce and water even while they are hot.
Adjust salt and pepper if necessary and add more sauce if needed. Cover with lid and rest for 2-3 minutes.
Serve after 3-minutes with your favorite sides or as it is.
