Turn the Instant Pot to "saute" mode. Add in the olive oil and let it heat up. Add in the ground beef and the onion and cook for 5-7 minutes, using a spoon to break up the meat.
Add in the remaining ingredients and give everything a good stir. Cook on manual high pressure for 12 minutes. Let it naturally release for 10 minutes. Release the steam, then stir. Serve with desired toppings and enjoy!
