Preheat your oven to 400°F and bring a large pot of salted water to a boil.
Trim the woody ends off the asparagus and toss the spears with 0.5 tsp of olive oil, a pinch of sea salt, and black pepper on a baking sheet.
Roast the asparagus for 10-12 minutes until they are tender and slightly charred.
Cook the whole wheat pasta according to the package instructions, ensuring you reserve 2 tablespoons of the starchy pasta water before draining.
Season the chicken breast with the remaining sea salt and black pepper, then sear in a skillet with 0.5 tsp of olive oil over medium-high heat until golden and cooked through.
In a small mixing bowl, whisk together the Greek yogurt, lemon juice, lemon zest, and minced garlic until the mixture is completely smooth.
Lower the skillet heat to low, then add the cooked pasta, roasted asparagus, and the yogurt mixture to the pan.
Gently toss all ingredients together, adding the reserved pasta water as needed to create a creamy, cohesive sauce.
Garnish the dish with fresh chopped parsley and serve immediately while warm.
