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 half of the olive oil, a pinch of salt, and pepper on a baking sheet; roast for 10-12 minutes until tender.
Cook the chickpea pasta according to package instructions, making sure to reserve 2 tablespoons of the starchy pasta water before draining.
Season the chicken breast with the remaining salt and pepper, then sear in a skillet over medium-high heat with the rest of the oil until golden and cooked through.
In a small mixing bowl, whisk together the Greek yogurt, lemon juice, lemon zest, minced garlic, and reserved pasta water until smooth.
Slice the cooked chicken into strips and combine with the pasta and roasted asparagus in the skillet.
Turn off the heat and fold in the creamy lemon sauce, tossing gently to coat everything evenly.
Garnish with fresh chopped parsley and serve immediately while warm.
