The flavors of the sauce were amazing. We opted for boneless chicken breasts instead of bone-in. We also might try adding a bit of tomato paste to thicken the sauce slightly.
2+ lbs. boneless, skinless chicken breasts
1/2 tsp salt, plus 1 tsp
1/2 tsp freshly ground black pepper, plus 1 tsp
1/4 cup olive oil
1 red bell pepper, sliced
1 yellow bell pepper, sliced
3 oz prosciutto, chopped
2 cloves garlic, chopped
15-oz can diced tomatoes, drained
1/2 cup white wine
1 Tbsp fresh thyme leaves, chopped
1 tsp fresh oregano leaves, chopped
1/2 cup chicken stock
2 Tbsp capers
1/4 cup chopped fresh flat-leaf parsley leaves (optional)
Season the chicken with 1/2 teaspoon salt and 1/2 teaspoon pepper. In a heavy, large skillet, heat the olive oil over medium heat. When the oil is hot, cook the chicken until browned on both sides. Remove from the pan and set aside.
Keeping the same pan over medium heat, add the prosciutto and cook for about a minute, then add peppers, season with salt and pepper and cook until the peppers have browned and the prosciutto is crisp, about 5 minutes. Add the garlic and cook for 1 minute. Add the tomatoes, wine, and herbs. Using a wooden spoon, scrape the browned bits off the bottom of the pan. Return the chicken to the pan, add the stock, and bring the mixture to a boil. Reduce the heat and simmer, covered, until the chicken is cooked through, about 20 to 30 minutes.
If serving immediately, add the capers and the parsley. Stir to combine and serve. If making ahead of time, transfer the chicken and sauce to a storage container, cool, and refrigerate. The next day, reheat the chicken to a simmer over medium heat. Stir in the capers and the parsley and serve.
