Place the salmon, cream cheese, lemon juice, and black pepper in your food processor bowl.
Process until smooth, about 5 minutes, stopping twice to scrape the sides with a spatula.
Transfer the mousse to a pretty serving bowl and serve it with cut-up veggies. Alternatively, transfer the mousse to a pastry bag and pipe it onto cucumber slices.
Garnish with chopped chives and serve.

Notes
The nutrition info includes cucumber and chives.
I don't add any salt to the mousse. Smoked salmon is very salty, so there's no need for added salt.
You can keep this mousse in an airtight container in the fridge for up to 4 days. Remove it from the fridge 20 minutes before you plan on enjoying it. While you can technically freeze this mousse for up to three months, its texture won't be as light after it's been thawed.
