Brown 1 pound ground beef in a skillet over medium-high heat. Drain any excess grease.
Place ¼ cup of the chopped cilantro into the bottom of a 6-quart slow cooker.

Stir all the ingredients together until well combined.
Cover and cook on Low for 6 to 8 hours or on High for 3 to 4 hours.
Just before serving, stir in the juice from 1 lime.
Top the soup with the remaining ¼ cup chopped cilantro.
Serve each bowl with shredded cheddar cheese.
Serve warm and enjoy.
