Preheat oven to 375°F. Season chicken with salt and pepper; lightly dust with flour, shaking off excess.
02 -
Heat oil in a braiser pan or large ovenproof skillet over medium-high heat. When oil shimmers, add chicken, skin-side down, in a single layer. Cook, flipping once, until browned on both sides, 6 to 8 minutes total. Transfer to a plate.
03 -
Add sausages to the same pan and cook, turning occasionally, until browned all over but not fully cooked through, about 5 minutes. Transfer sausages to the plate with the chicken.
04 -
Reduce heat to medium. Add shallots and garlic to the pan and cook, stirring occasionally, until softened and golden in some areas, about 3 minutes.
05 -
Add rosemary and pickled pepper brine to the pan. Cook until liquid mostly evaporates, a few seconds. Add chicken broth and lemon juice; boil until liquid reduces by half, 8 to 10 minutes.
06 -
Return chicken and any accumulated juices to pan, skin-side up, along with the halved peppers. Transfer the entire pan to the oven and roast for 15 minutes.
07 -
Slice sausages on the bias into thirds. Nestle the sausage pieces into the skillet. Continue roasting until the chicken registers 165°F on a meat thermometer and the sausages are fully cooked, about 5 minutes more.

Serve warm with crusty bread, if desired.
