Dredge chicken in flour. Heat olive oil in a large skillet over medium heat until it shimmers, and sauté the chicken. When chicken is golden brown, add the shrimp and cook for 3 minutes or until the shrimp is cooked through. Add prosciutto and garlic and sauté for approximately 30 seconds. When prosciutto starts to curl, deglaze the pan with white wine and the chicken stock. Simmer with chicken and shrimp until the sauce starts to thicken. Add cannellini beans and simmer until heated through.
