Add 1 cup of water to the bottom of the Instant Pot, place the rack inside the pot and place the vegetables on the rack.
Place the lid on the Instant Pot and seal shut. Turn the Instant Pot on, touch 'Manual' and then 'Steam'. Set the timer to 12 minutes.
When the vegetables are done cooking, allow the Instant Pot to vent naturally or you can carefully turn the vent to release the pressure manually (standing back to avoid the steam). Remove the vegetables from the Instant Pot and serve.
