1. Literally, to improve or enhance the flavor of some food with salt, pepper, or another kind of seasoning or flavoring. A noun or pronoun can be used between "season" and "with." They season the meat with coarse sea salt, then grill it very quickly on either side. I like to season my sauces with paprika and a bit of cayenne.

2. By extension, to make something more interesting, dynamic, or lively by the addition of something else. Why they felt the need to season the original story with all these huge CGI action scenes is beyond me. You've packed a lot of great information into your presentation, but try to season it with some humor or interesting anecdotes. It's just a bit dry as it is.
