1. Heat the oil in a large saucepan over a high heat. Season your chicken thighs with salt and pepper, then cook for 4 minutes, turning. Remove and set aside.

5. Remove the chicken, shred the meat and return to the saucepan.
6. Season to taste with salt and pepper. Stir through parmesan (optional).
7. Divide into bowls and top with baby spinach.
