Heat oil in a large skillet over medium-high heat. Add ground pork and cook until no longer pink, crumbling as you go. Drain grease and add the ground pork to the slow cooker.
Turn on the pressure cooker and select sauté. Once hot add oil to the pot. Add the ground pork and the onion and cook 3-5 minutes until the pork is no longer pink. Crumble the meat as it cooks. Add the garlic and cook an additional minute.
Add all remaining ingredients. Stir to mix well.
