Preheat oven to 375°F.
Cut chicken in half to make 4 pieces, leaving the bone on.
Heat oil in a large, oven safe sauté pan or cast iron skillet with straight sides over medium-high heat.
Season the chicken with salt and pepper and brown 2-3 minutes per side.
Remove chicken and set aside.
Lower heat to medium and add onion, chicken sausage, cauliflower florets, garlic and cherry peppers.
Sauté, stirring frequently, for 2-3 minutes until vegetables and sausage start to brown.
Add the white wine, cherry peppers and additional optional liquid.
Raise heat and allow to boil for about 2 minutes before adding chicken stock.
Add chicken breasts back into pan, bone side down, sprinkle rosemary on top, bring to a boil and then place the pan in the oven, uncovered.
Cook for 20-25 minutes or until chicken reaches 165°F.
Remove from oven carefully, with towel or kitchen gloves, serve and enjoy!
