Heat gnocchi in boiling salted water until heated through and they begin to float, about 90 seconds.
Gently heat Tuscan Butter in a saute pan over medium heat.
Add Chicken, broth, Tomatoes and lemon juice. Bring to a gentle simmer. Season with S&P.
Drain gnocchi well and add to the pan.
Add spinach, Pesto and 1st portion of parmesan. Gently toss to coat the gnocchi evenly with the sauce.
Continue cooking to heat through, while ensuring the sauce does not over-reduce. Taste and adjust seasoning as needed.
Using a rubber spatula, transfer immediately to a warm bowl, pulling all the sauce from the pan into the bowl.
Garnish with remaining parmesan evenly distributed over the gnocchi.
