Basic Trope: Instead of killing the defeated/captured hero, the villain cooks him/her a meal.
Straight: Emperor Evulz's Mooks have successfully captured Alice and Bob. His first act is to bring them into his lair and cook them a meal.
Exaggerated: Emperor Evulz has beaten Alice and Bob within an inch of their lives during their last encounter. He then immediately calls for medical support, performs CPR on both of them until the doctors arrive, sees that their clothes are mended, and has their families informed that they will live. When they awaken, he makes sure that they get everything they want or need prior to their next encounter.
Downplayed: Emperor Evulz locks them in his dungeon, but makes sure they're fed and reasonably kept.
