Heat a large heavy bottom pot over medium-high heat.
Add cooking oil and pork (or chicken) to the pot. Season generously with salt and pepper. Sear the meat on all sides until nicely browned.
Add the prepared chili verde to the pot and mix thoroughly, making sure to scrape the bottom of the pot with a spoon so you get all the brown bits.
Cover the pot and lower the heat to a simmer and cook for 2-3 hours, until the pork or chicken is very tender.
Add the water, lime juice and cilantro. Stir until combined. Taste and season with more salt if necessary.
Add a touch of apple cider vinegar if you want, but it isn’t necessary.
Enjoy!
