In a mixing bowl, crack the eggs and beat them.
Add sea salt, heavy cream, and softened cream cheese to the beaten eggs, mixing until well combined.
Stir in the chopped smoked salmon and optional dried dill for added flavor.
Grease the slow cooker with a small amount of cooking spray.
Pour the egg and smoked salmon mixture into the slow cooker.
If desired, sprinkle grated Parmesan cheese over the top for added flavor.
Cover the slow cooker with the lid.
Cook on low heat for 2-3 hours or until the quiche is set and slightly golden on top.
Once cooked, cut into servings and serve the smoked salmon "quiche" hot.
