Marcus, when it says salmon is smoked in a way it's a process of cooking, if your package says or any package says "smoked" salmon well the answer is no you don't need to cook it. You can eat it out of the package if you wish. Sugar Pies suggestions of eating it is correct.
One of the popular is with bagels, toast the bagel or how it comes, spread cream cheese and top with slices of smoked salmon, now close the top, and eat your eart out.
There is one I stumbles on, and you should try. A baguette, slice it in half (Down the side) open, place under the grill till golden, take out of oven, on the base give a good spread of cream cheese (Philly), and on the top a light spread. On the base spread ripped romain lettuce, sprinkle capers a long the lenth of the baguette, top with slices of smoked salmon, replace the top, place a toothpick lets say every 4 inches, and cut between the toothpicks, place on a serving plate or dish, and there you have it a healthy snack.
