Preheat your oven to 400 degrees f.
Pound the chicken breast to an even thickness and rub lightly with sea salt, pepper, Italian seasoning, and your oil.
In a medium bowl combine your fresh diced tomatoes, minced garlic, balsamic and chopped artichoke hearts. Season lightly with sea salt and pepper.
Spread half of the artichoke-tomato mixture in a large baking dish. Add your chicken in a single layer, then top with the remaining artichoke-tomato mixture.
Top with freshly shredded mozzarella.
Bake for 35-40 minutes, or until the chicken is cooked through.
Top with freshly chopped basil or parsley if desired.
