Trim any excess fat from the pork shoulder and cut it into large chunks.

In your slow cooker, combine the pork with orange juice, lime juice, minced garlic, chopped onion, cumin, oregano, chili powder, salt, pepper, and bay leaves. Mix them well.

Cover the slow cooker and set it to low for 8 hours or high for 4-5 hours.

Carefully remove the pork from the cooker, discard any leftover fat, and shred the meat into bite-sized pieces.

Spread the shredded pork on a baking sheet and place it under the broiler for 5-8 minutes, until the edges are golden brown.

Drizzle a bit of the cooking liquid over the pork before serving.
