Chipotle Pork Posole

In a large saucepan, heat oil over medium. Season pork with salt and pepper. Cook until browned on all sides, 6 to 7 minutes. Transfer pork to a plate, and set aside (reserve pan). Place onion and garlic in pan; season with salt and pepper. Cook over medium, stirring occasionally, until onion begins to soften, 4 to 5 minutes.

Add chiles, and cook until fragrant, about 1 minute. Add broth, hominy, tomatoes, pork, and 2 cups water. Bring to a boil; reduce to a simmer. Cook until an instant-read thermometer inserted in center of pork registers 145 degrees, 3 to 4 minutes.

Transfer pork to a work surface, and shred with 2 forks; return to pan. Top soup with cilantro, and, if desired, serve with lime wedges.
