Preheat oven to 350 degrees.
Butter two baking dishes, the size to hold two eggs.
Crack two eggs into each dish and bake for 20 minutes or until whites are set.
In a saute pan, add leftover shallot cooking in butter until tender. Add capers and fresh herbs and saute for 1-2 minutes. Add cooked salmon and gently stir until salmon is heated through.
Top baked eggs with a spoonful salmon herb mixture. Sprinkle with scallion and lemon zest.
