Rotelli with Roasted Asparagus, Chicken, and Lemon Thyme

Preheat oven to 450 ° F. Bring a large pot of salted water to a boil. Toss asparagus with 1 Tbsp of the olive oil, thyme, and 1/4 tsp of the salt in a large roasting pan. Spread out into an even layer and roast 8 to 10 minutes, until crisp-tender. While asparagus roasts, add pasta to the boiling water and stir a few times; cook according to package directions. Meanwhile, heat remaining olive oil in a large nonstick skillet over medium-high heat; add chicken and sprinkle with 1/4 tsp of the salt. Stir-fry 3 minutes, until browned. Add lemon zest; stir-fry 1 minute longer, until chicken is cooked through. Remove from heat; stir in lemon juice, remaining 1/4 tsp of the salt, and pepper. Drain pasta and return to pot; add asparagus and chicken mixture and toss. Divide over 6 plates. Top each serving with Parmesan cheese.
