Dredge chicken pieces in flour and brown them in a hot skillet with olive oil. Set aside.
Sauté sausage until browned, then add mushrooms, onion, and bell peppers.
Stir in garlic and cook until fragrant, about 1 minute.
Add cubed potatoes and cook for 5–6 minutes to lightly brown them.
Deglaze the pan with white wine and brine from Peppadew peppers.
Return the chicken to the pan along with chicken broth, Italian seasoning, and salt.
Add halved Peppadews and let the mixture simmer until potatoes are fork-tender.
Garnish with fresh parsley before serving hot.
