Bring a pot of water to boil and cook the chickpea pasta according to package directions, adding the asparagus spears for the last 3 minutes of cooking.
While pasta cooks, season the salmon fillet with half of the sea salt and black pepper.
Heat olive oil in a non-stick skillet over medium-high heat and sear the salmon for 4-5 minutes per side until golden and cooked through.
Remove salmon from the pan and flake it into large chunks using a fork.
In a small bowl, whisk together the Greek yogurt, lemon juice, minced garlic, and fresh dill to create the sauce base.
Drain the pasta and asparagus, reserving 2 tablespoons of the hot cooking water.
Toss the hot pasta and asparagus with the yogurt sauce, flaked salmon, and reserved water until the sauce is velvety and coats everything evenly.
Season with the remaining sea salt and black pepper before serving immediately.
