Place the frozen meatballs and 1 cup of water into your Instant Pot bowl.
Add the lid, per the instructions for your pressure cooker. And make sure the vent is in the "sealing" position.
Set the manual high pressure for 5 minutes, when the time is up, let it naturally release.
When the Instant Pot pressure is completely released, and the pin is down. Remove the lid, and drain the meatballs.
Pour in your sauce ingredients, and mix well. Then press the "saute'" button and saute' the meatballs with the sauce for about 3-4 minutes.
Note: You are only wanting the sauce to heat up, and mix well into the meatballs, once everything is hot, hit cancel.
Plate, serve and enjoy!
