Make zucchini noodles using spiralizer or a vegetable peeler.
Heat 1 tablespoon of olive oil in a large pan over medium heat.
Season the chicken with salt and pepper and place the chicken in the pan for 8-10 minutes, ensuring it is cooked all over.
Once the chicken is cooked through, transfer to a plate and set aside.
Next, cook the zoodles. In the same pan, add the remaining tablespoon of oil, pesto, tomatoes and zucchini noodles.
Stir well, until the zoodles are coated with the pesto.
Add the chicken back into the pan, along with the parmesan cheese and toss. Add more salt and pepper if necessary.
Serve with fresh basil and chili flakes.
