Bring a large pot of salted water to a boil. Add the gnocchi and cook according to package instructions, typically around 2-3 minutes or until they float. Drain and set aside, reserving a cup of pasta water.
Heat a large skillet over medium heat and add the olive oil. Add the diced chicken, season with salt and pepper, and cook for about 5-7 minutes until golden brown and cooked through. Remove from skillet and set aside.
Add the grated Parmesan cheese, stirring until melted. If too thick, add reserved pasta water until desired consistency is reached. Stir in the fresh spinach and allow to wilt for 1-2 minutes.
Return the cooked chicken to the skillet, mix with the sauce, and gently fold in the cooked gnocchi. Heat through for another minute. Finish with a squeeze of lemon juice and adjust seasoning as needed.
Serve immediately, garnished with additional Parmesan cheese if desired.
