Heat the oven to 155°C / 315°F degrees.
Pat the pork with a paper towel to blot any extra moisture. Season with sea salt and pepper.
Heat 2-3 tablespoons olive oil in an ovenproof pot (like a Dutch oven).
Add 3-4 pork pieces and brown all over. Transfer to a plate and repeat until all are browned.
Move all the pork back into the pot on high heat. Carefully add the wine and let the alcohol evaporate.
Add the onions, chickpeas, and tomatoes and season with sea salt, freshly ground pepper, cumin, and cayenne pepper (to taste). Stir gently. If needed, add a little saved chickpea water(see recipe notes).
Cover and place the pot in the oven. Cook for 60 minutes.
Stir and add the sun-dried tomatoes, cover and continue cooking in the oven for 30 more minutes.
Uncover, add a little chickpea water if needed, stir, and continue cooking for 30 more minutes.
Let the pork stew sit for 15 minutes. Adjust sea salt and pepper to taste and serve.
