Instant Pot
Heat Instant Pot to saute function.
Cut each pork tenderloin into chunks about 4 inches long.
Add in oil. Once oil is hot, add in pieces of pork tenderloin to Instant Pot and saute for 2 minutes on each side just to brown.
Set pork aside on a plate.
Add diced onion to hot IP and saute for 2-3 minutes before adding garlic. Once garlic is fragrant, turn off IP.
Add pork back into IP, and then add all seasonings and apple cider on top.
Seal the lid and manually cook for 25 minutes. Once 25 minutes is up, let IP naturally release for 10 minutes. After 10 minutes is up, quick release the rest.
Turn off IP and take off lid. Let pork rest for 10 minutes before shredding. It should be easy to peel apart, if not, it may need more cook time.
Shred your meat and mix into all the juices. Enjoy!
