Turn your IP on sauté and add olive oil.
Once hot, add garlic and cook until a golden color.
Then add all remaining ingredients, EXCEPT AVOCADO! (You do not add avocado to the Instant Pot at all.) Mix ingredients well with wooden spoon.
Place lid on, and put on Manual High Pressure for 10 minutes. Do a QPR.
Once pressure is released, removed lid.
Turn pan back onto sauté mode, and stir the meat to break it up into little chunks.
Keep on sauté mode until liquid has been reduced by half.
Allow to cool and serve in a bowl, and then surround it with your diced avocado. Yum!
