Season the chicken: Pat the chicken pieces dry with a paper towel. Season both sides with salt, black pepper, and garlic powder. Drizzle with white vinegar and set aside for a few minutes while you prep the remaining ingredients.
Sear the chicken: Heat olive oil in a large skillet or Dutch oven over medium-high heat. Once hot, add the chicken pieces in a single layer. Sear for 5-6 minutes per side until golden brown. Remove the chicken from the pot and set aside.
Cook the chorizo and vegetables: In the same pot, add the sliced turkey sausage. Cook for 3-4 minutes until lightly browned. Add the sliced red bell pepper and onion, stirring occasionally until softened (about 5 minutes).
Add spices and cherry peppers: Stir in the dried oregano, chopped rosemary, and cherry peppers. Cook for 1 more minute to enhance the flavors.
Simmer with chicken broth: Pour in the chicken broth and bring to a boil, scraping the bottom of the pot to incorporate the browned bits.
Return the chicken and simmer: Nestle the reserved chicken into the sauce. Reduce the heat to medium-low, cover, and simmer for 25-30 minutes, or until the chicken is tender (internal temperature: 165°F / 75°C).
Serve: Remove from heat, let it rest for 5 minutes, and serve.
