To the pan that you seared the pork in, add the wine, onion, pepper, and sweet potatoes and cook until the wine is gone, about 3-4 minutes. Transfer these to the Dutch oven with the pork, and add the stock, 2 teaspoon of kosher salt, and the chickpeas. Bring just barely to a boil, cover, and put in the oven for 20 minutes. Remove the lid and continue to cook for 20 more minutes. Check the pork for doneness and add salt to taste if needed. Then serve alongside the rice and garnish with parsley.
