Add the sliced zucchini, and cook for a few minutes until lightly golden.
Add the canned cherry tomatoes, balsamic vinegar and 1 ½ Tablespoons of Italian herbs. Stir until simmering and combined.

Place the browned chicken breasts on top of the gnocchi, sprinkle with the remaining Italian herbs then bake in the oven uncovered for 20 minutes or until the juices of the chicken run clear when pierced with a skewer.
