Step 1

Trim and discard excess fat from the pork.

Step 2

In a small bowl, combine chili powder, cumin, oregano, salt and pepper. Generously season the pork on all sides.

Step 3

Add the seasoned pork to the bottom of the slow cooker. Add garlic, chopped onions, orange juice, and lime juice.

Step 4

Cover and cook on LOW for 7-8 hours or high for 4-5 hours.

Step 5

Remove pork from the slow cooker, shred the meat, and return it to the pot. Taste and add more seasonings and salt and pepper, if needed.

Step 6

At this point you can eat the pork as it, or (to be truly authentic) you can place the meat on a baking sheet and broil it for 2-3 minutes until the edges are crispy.

Step 7

For tacos, serve warm inside corn tortillas, garnished with cilantro. Add salsa or pico if desired.

Step 8

Serve with a side of authentic Mexican rice and refried beans.

Step 9

Store leftovers in an airtight container in the refrigerator for 3-5 days.
