Cut the chicken thighs and Italian sausage into bite-sized pieces. Heat olive oil in a large pan and add the sausage and chicken. Brown them for about 6-8 minutes, then remove from the pan.
In the same pan, add onions, red peppers, and yellow peppers. Add a splash of olive oil and let them soften for about 5-6 minutes.
Create a clear spot in the pan and add garlic with a little more olive oil. Let it become fragrant, then mix it with the vegetables.
Pour in white wine or vermouth and let it reduce by half, which should take about 2 minutes.
Add chicken broth, red wine vinegar, chopped pickled cherry peppers, and oregano. Let it simmer and mix well.
Return the browned sausage and chicken to the pan, along with any juices. Keep it on a low simmer for 6-8 minutes to finish cooking and thicken the sauce.
Add a little extra brine from the pickled cherry peppers for additional flavor. Season with salt and pepper to taste.
Serve the Chicken Scarpariello over cooked rigatoni, topped with parmesan cheese, a drizzle of extra virgin olive oil, and a sprinkle of parsley.
