Add all of the ingredients except for beans and corn in a slow cooker.
Cook for 4 hours on HIGH or 6 on LOW. I really prefer using the LOW setting if time allows.
Once cooked, shred the chicken, then return to the crock-pot together with the Cannellini beans and corn. Place the lid back on and cook for an additional 20-30 minutes.
Sprinkle with fresh chopped cilantro/parsley and jalapeno slices to serve.
