Heat the oil in a large, wide skillet over medium high heat. Season the chicken on both sides. Add chicken to the hot pan; cook for 3-4 minutes per side until golden brown and cooked through. Remove chicken and set aside.
In the same pan, add the oil, shallots, and sun dried tomatoes. Sauté for 5 minutes until the shallots are golden and softened.
Add the gnocchi and broth. Simmer for another 5 minutes, until the gnocchi are tender.
Add the cream and spinach; stir to combine. Keep it at a low simmer for a few minutes to further thicken the sauce.
Add salt, pepper, and fresh thyme leaves to taste. Add chicken back in.
Serve pieces of chicken with a scoop of the creamy gnocchi and a spoonful of the extra sauce over the top. Add a sprinkle of Parmesan on top, or into the sauce, for even more flavor.
