In the Instant Pot, turn on the sautee mode. Heat up some avocado oil and put in the grass-fed beef stew meat! Season with some salt + pepper! You just want to brown the outside of the meat. (Feel free to skip this step if you're using a slow cooker!)
Turn off the IP and put the rest of the ingredients into the pot. Mix well!
Put lid on and make sure it's set to sealed. Cook on high pressure for 18 minutes.
