Place quinoa, water, and salt in an Instant Pot. Place lid on and seal. Make sure the valve is set to "sealing". Select "manual" and set Instant Pot to 1 minute.
Once the 1 minute is up let the quinoa sit in the Instant Pot for 10 minutes to do a natural pressure release. Then carefully, move the valve to "venting". Once the pressure is released remove the lid, mix well and serve.
