Put 1/2 cup beans in a small bowl and mash with a fork (this will help thicken the casserole). Add the remaining beans and set aside. Toss breadcrumbs with 1TBS oil in a small bowl. Heat a large skillet over medium-high heat. Add the breadcrumbs and cook, stirring often, until golden and crisp, 2 to 3 minutes. Transfer to a plate and set aside.
Heat the remaining 1 TBS oil in the skillet over medium heat. Add chicken in a single layer and cook until browned, turning once, 2 to 3 minutes per side. Transfer to a plate. Add onion and garlic to the skillet and cook, stirring occasionally, until the onion is softened, about 5 minutes. Add rosemary, thyme and pepper and cook, stirring, until fragrant, about 30 seconds. Add wine; increase heat to high and cook, stirring with a wooden spoon to scrape up any browned bits, until the wine has reduced by about half, 1 to 2 minutes. Add broth, kielbasa, the reserved beans and chicken; bring to a boil. Reduce heat, cover and simmer until the chicken is cooked through; check at 10 minutes. If the mixture is too liquid, remove lid, and continue to simmer an additional 5-10 minutes. Top with the toasted breadcrumbs and parsley. 6 servings.
