Slice and toast bagel.
Make cream cheese: chopping fillings and combining in a bowl. Season to taste.
Make the omelette: Whisk 2 eggs and then pour into the pan. Let the eggs cover the whole bottom of the pan in an even layer. Let them sit for about a minute on low heat.
Add capers a small scoop of cream cheese and dill. Fold eggs on each side making a little package for the cream cheese so it gets a little melty.
Assembly: Add cream cheese to bagel along with layers of smoked salmon, and the omelette. Top with arugula and red onion. Enjoy!
