Heat a large skillet or pot over medium-high heat. Add the oil and allow to heat through. Season the pork with 2 teaspoons salt and 2 teaspoon black pepper. Make sure it's liberally seasoned. Sear the pork on all sides just until crispy and browned. Transfer to a slow-cooker. Add the chopped veggies, remaining 2 teaspoons black pepper and 2 teaspoons salt, tomato paste and cheerwine.
Cook on low for about 6 to 8 hours or on high for about 3 to 4 hours. Remove pork from stew and slice or shred. Garish with parsley. Enjoy!
