Boil a large pot of salted water and cook the pasta until al dente.
While the pasta cooks, shred the cooked chicken into bite-sized pieces.
In a large skillet, heat a drizzle of olive oil over medium heat.
Add the shredded chicken to the skillet and sauté for 2-3 minutes until warmed.
Once the pasta is cooked, reserve ½ cup of pasta water, then drain the pasta.
Add the drained pasta to the skillet with the chicken.
Stir in the basil pesto and mix well to combine.
If the pasta seems dry, add reserved pasta water a little at a time.
Fold in the cherry tomatoes and season with salt and pepper.
Serve garnished with grated Parmesan and fresh basil leaves.
