Set you Instant Pot to the sautee setting. Add 1 tbsp oil and brown meat on all sides. You may have to do this in a couple of batches.
Remove meat from Instant Pot and set aside. Deglaze the pot with 2 tbsp of broth or water. Add the chopped onions, garlic, chopped red peppers, and ginger. Cook for about 3 minutes. Turn off sautee setting.
Return meat to Instant Pot. In a bowl, whisk coconut milk, beef stock, arrowroot flour, nut butter, curry paste, coconut amino, fish sauce, and honey. Pour over meat.
Cook, covered, on low 7-8 hours or until meat is tender.
Serve and top with chopped nuts and cilantro. Enjoy!
