Place the cottage cheese in a chilled mixing bowl and spread it slightly with a spoon.
Add the chopped smoked salmon, diced avocado, and minced red onion to the bowl.
Drizzle the lemon juice over the mixture to provide acidity and prevent avocado oxidation.
Add the fresh dill, chives, and cracked black pepper.
Gently fold the ingredients together using a silicone spatula until evenly distributed, being careful not to over-mix or mash the avocado.
Transfer the salad to serving bowls and finish by sprinkling everything bagel seasoning over the top.
Serve immediately or refrigerate for up to 2 hours.
