4. Meanwhile, place a large pot of water on the stove, season with salt and bring to a boil. Once the water is at a rolling boil, add the pasta and cook according to package instructions (I left mine a bit al dente). 5. Once the chicken has finished cooking, let the breasts rest for about 5-10 minutes then thinly slice going against the grain. 6. To your serving bowl, add the pasta and the pesto and gently toss together. 7. Serve with the grilled chicken, a lemon wedge, and freshly sliced parmesan.
