You can mix it with herbs & seasonings, of your choice >>>
and then, sour cream, and serve as a dip. Or, you can do a similar thing with the herbs, etc, & mix with a bar or two of cream cheese, then line a bowl with plastic wrap & put the mixture in, and, voila! a "mousse".
Or you can mash it up, add some seasonings, some bread crumbs & beaten eggs, and have salmon croquettes.
Have fun! Happy Holidays!
