In a large pot of boiling salted water, cook the gnocchi according to package instructions until they float to the top, about 2-3 minutes. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the chicken pieces, season with garlic powder, salt, and pepper, and cook until the chicken is browned and cooked through, about 5-7 minutes.
Reduce the heat to low and pour in the heavy cream. Stir to combine, then add the Parmesan cheese and Italian seasoning. Cook for another 2-3 minutes until the sauce thickens slightly.
Add the cooked gnocchi and fresh spinach to the skillet, stirring gently to coat everything in the creamy sauce. Cook for an additional 2 minutes until the spinach wilts.
Serve immediately, garnished with fresh parsley.
