Add the Olive Oil, and Butter to the Instant Pot, and press the SAUTE button.
Sprinkle the pork chops with the garlic salt, seasoned salt, and seasoned pepper, on both sides.
When the butter melts, add the Pork Chops to the Instant Pot, and brown them on both sides, about 10 minutes each side.
If the Instant Pot gives a 'HOT' reading on the readout, turn off the SAUTE setting, and let it cool off for a couple of minutes.
Turn the SAUTE setting back on, and finish browning the pork chops.
When the pork chops are browned, turn off the SAUTE setting, and remove the pork chops to a plate.
Add the beef broth, balsamic vinegar, Stevia, and minced garlic.
Let the sauce sit in the Instant Pot for about 10 minutes.
With a spoon, stir the sauce, scraping the bottom of the Instant Pot, removing any bits that are stuck.
Add the Pork chops back into the Instant Pot, into the sauce.
Place the lid on the Instant Pot until it beeps and locks. Make sure the pressure valve is set to 'SEALING'. Press the MANUAL button, and set the time to 20 minutes.
The Instant Pot will build pressure, and cook the Pork Chops. When the Pork chops are done, the Instant Pot will beep, and go to 'OFF'. Allow to NATURAL RELEASE. Make sure all the pressure has been released by checking the 'FLOAT VALVE'. If the Float valve is down, the pressure has been released, if it's not down, move the pressure valve from SEALING, to VENTING, and make sure all the pressure is released before opening the lid.
Remove the lid to the Instant Pot, and remove the pork chops to a platter or plates to serve. Ladle the sauce over the chops, or place the sauce in a gravy boat, or dish, and serve on the side.
