Step 1

Preheat your oven to 375 degrees f.

Step 2

Heat oil in a skillet over medium-high heat, add in chicken and season with sea salt and freshly ground black pepper.

Step 3

Cook, stirring occasionally, until golden brown on the sides and almost cooked through.

Step 4

Transfer the chicken to a 8x8 baking dish (sprayed or brushed with oil to prevent sticking), top with chopped tomatoes, oregano, garlic and a drizzle of balsamic vinegar.

Step 5

Sprinkle with mozzarella cheese.

Step 6

Place your casserole into the preheated oven, uncovered, and bake for 18-20 minutes, just until cheese is melty and sauce is bubbling at the bottom of the dish.

Step 7

Remove from the oven, cover, and allow casserole to rest for 5 minutes, then garnish with fresh basil and enjoy!
