Pour 1 cup of filtered water into the inner pot of the Instant Pot®, and insert the trivet. On a piece of aluminum foil, mix together all ingredients. Form into one large loaf. Move this (and the aluminum foil) to rest on top of the trivet.
Close the lid, set the pressure release to Sealing, and select Manual/Pressure Cook. Set the Instant Pot® to 40 minutes on high pressure and let cook.
Once cooked, let the pressure naturally disperse from the Instant Pot® for about 10 minutes, then carefully switch the pressure release to Venting. Open the Instant Pot®, serve, and enjoy!
