Human: I need to know how to prepare a ham. Assistant: 
To prepare a ham, you will need to begin by selecting one that is already cooked and ready to eat. Then, you should trim off any visible fat or gristle from the meat. Next, cut it into thin slices and arrange them on a platter. Serve with your favorite side dishes and condiments such as mustard, mayonnaise, or horseradish sauce. Enjoy!
