Preheat the oven to 400℉ (205℃) and line a baking sheet with parchment paper.
Add the chicken and asparagus to the baking sheet and drizzle with oil. Bake for 25 minutes or until the chicken is cooked through. Chop the chicken and asparagus into bite-size pieces.
Meanwhile, cook the pasta according to package instructions.
To assemble the pasta, mix the chicken, asparagus, pasta, pesto, lemon juice, and parmesan together. Season with salt and pepper. Divide evenly between bowls and enjoy!
