Season the chicken with salt and pepper and dice into cubes. Place a large skillet over medium heat and add in the olive oil. Once oil heats, add in the chicken and cook until done, 5-10 minutes.

Once chicken is cooked, remove from the skillet and transfer to a small pot and set over medium heat. Add in the tomato sauce and let cook, about 3 minutes until sauce is heated.

While sauce heats, add the zucchini noodles into the same large skillet and toss for 2-3 minutes or until cooked to your preference. Once cooked, transfer to a bowl and top with chicken and sauce. Top the pasta with freshly grated parmesan cheese. Serve immediately.
