Place the eggs in a pot large enough to hold them in a single layer. Cover the eggs with cold water and bring to a full boil over high heat. As soon as the water boils, set a timer for 8 minutes.
Then drain the eggs and fill the pot with cold water. Set aside until the eggs are cool.
Peel the eggs and then slice them in half lengthwise. Remove the yolks carefully. Place the yolks in the bowl of an electric mixer fitted with the paddle attachment and arrange the whites on a platter in a single layer with the cut sides up and sprinkle with salt.
Add sour cream, cream cheese, mayonnaise, lemon juice, chives, salmon, salt, and pepper to the egg yolks. Beat on medium speed until fluffy. Fill the egg whites with the egg yolk mixture with a small spoon. Refrigerate while you make the coffee.
Brew and prepare the coffee to your liking.
Garnish the eggs with a dollop of salmon roe (if using) and some extra chopped chives. Sprinkle with salt and pepper and serve.
Add the cereal and milk into a bowl and serve immediately with eggs.
