I need to know how to prepare a ham.

To prepare a ham, start by selecting one that is already pre-sliced and packaged in a vacuum sealed package. Make sure it has been properly stored at the right temperature for the best flavor. Next, remove the packaging and rinse off any excess salt or other preservatives. Then, place the ham in an oven-safe pan and heat it in the oven at 350 degrees Fahrenheit until the internal temperature reaches 140 degrees Fahrenheit. Let it cool before slicing and serving.
