Place milk and breadcrumbs in separate shallow bowls. Dip chicken in the milk, then coat with breadcrumbs. In a frying pan over medium heat, fry chicken in butter on both sides, until the juices run clear. Remove from frying pan and keep warm.
Add the stock to the frying pan; bring to a boil over medium heat. Stir to loosen browned bits from pan. Stir in the cream and pimentos; simmer and stir for one minute. Reduce heat; add the Parmesan cheese, basil and black pepper. Simmer and stir until heated through. To serve, pour the sauce over the chicken.
