The recipe requires just 20 minutes of active time: after a bit of chopping, you just dump the ingredients in the slow cooker and let it do the work. Adding a squeeze of lime juice and a sprinkle of cilantro just before serving brightens up the flavors. Top it with some shredded cheese, if you'd like, or serve it as-is to keep it vegan.
