Combine the chopped smoked salmon, mayonnaise, lime juice, extra virgin olive oil, and sea salt in a small mixing bowl, stirring until the ingredients are thoroughly incorporated.
Arrange the shredded romaine lettuce evenly across a serving platter or wide salad bowl, then sprinkle the onion flakes evenly over the greens.
Spread the creamy smoked salmon mixture directly over the bed of lettuce, then elegantly arrange the sliced avocado on top and serve immediately.
Chill Your Platter: For the crispest romaine lettuce and a refreshing bite, chill your serving platter or salad bowl in the fridge for 10 minutes before assembling.
