Combine the salt, pepper, and oregano. Season the pork roast generously with the mixture.

Juice the oranges then put the oranges and juice put in slow cooker with cinnamon, chili powder, and garlic and stir to combine.

Place the pork in the slow cooker then add whatever liquid you are using.

Set to cook on low for 8 hours. The meat is done when it is tender and falling apart.

Let it cool enough to handle, then lift the meat from the juices and place in a large bowl. Shred the meat.

(For best results) In a large saute pan, heat the vegetable oil over high heat. Press the meat into the oil and fry until crusty on one side.

Serve on tortillas with salsa.
