Unwrap the pork from the mesh and cut it into 4 equal pieces. Evenly rub the seasonings over the pork and brown on all sides. Set aside.
Stir in the zest and juice of 1 orange then add the browned pork pieces and stir briefly to combine. Cook in an Instant Pot or slow cooker.
Shred the pork with 2 forks, transferring it to a bowl first if this makes it easier to shred. Then, broil on a baking sheet for crispy edges and serve!
