Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus spears and toss them on the baking sheet with olive oil, half the sea salt, and half the black pepper.
Roast the asparagus for 10-12 minutes until tender and slightly charred at the tips.
While the asparagus roasts, bring a small pot of water to a boil, then carefully lower the eggs into the water and simmer for 6.5 minutes for a soft-boiled yolk.
Immediately transfer the eggs to an ice bath for 2 minutes to stop the cooking, then peel and slice them in half.
In a small mixing bowl, whisk together the Greek yogurt, lemon juice, lemon zest, fresh dill, fresh chives, and the remaining salt and pepper.
Arrange the roasted asparagus on a plate, drape the smoked salmon over the spears, and place the halved eggs on top.
Spoon the creamy herb yogurt sauce over the eggs and salmon and serve immediately.
