Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Trim the woody ends off the asparagus and toss the spears with olive oil, sea salt, and black pepper on the prepared baking sheet.
Roast the asparagus for 12-15 minutes until tender and slightly charred at the tips.
Bring a medium pot of salted water to a boil and cook the chickpea pasta according to package directions, reserving 2 tablespoons of pasta water before draining.
Season the chicken breast with a pinch of salt and pepper, then sear in a non-stick skillet over medium heat for 6-7 minutes per side until fully cooked.
In a small mixing bowl, whisk together the Greek yogurt, lemon juice, lemon zest, minced garlic, and the reserved pasta water to create a smooth, creamy sauce.
Slice the cooked chicken breast into thin strips.
Drain the pasta and return it to the pot, then gently fold in the creamy lemon sauce, roasted asparagus, and sliced chicken.
Garnish the dish with fresh chopped parsley and serve immediately while hot.
