Add the garlic cloves, quartered onions, and cubed pork to the electric pressure cooker insert. Sprinkle the spice mixture over everything. Using your hands, toss the garlic, onions, and pork around in the spices, rubbing the spices into the meat. Add the orange and lime juice to the pressure cooker.
Place the lid on and lock it. Cook for 25 minutes on high pressure. Depending on your preference, you can allow the pressure to release naturally or do a quick release.
Remove the sheet pan from the oven and toss the meat around a bit with tongs. Pour some more of the juices over the meat and broil for 2-3 additional minutes.
Remove from the oven, top with chopped cilantro, and serve immediately.
