Season chicken thighs with salt and pepper. Sear in oil until golden on both sides; remove and set aside.
Add sausage links to the same pan, cook until browned, then remove.
Sauté sliced onion, red bell pepper, and garlic in the remaining oil.
Add pickled cherry peppers and their juice; stir well for 2–3 minutes.
Pour in white wine, scraping up brown bits. Let it reduce slightly.
Add chicken stock, then return chicken and sausage to the pan.
Simmer on medium-low for 20–25 minutes until everything is cooked through and the sauce thickens.
Garnish with fresh parsley, chili flakes, and serve hot.
