Just toss together two cups of spinach, one large diced tomato, olive oil and minced garlic. Spread it onto a baking sheet and roast in the oven for about 10 minutes.
Drizzle your chicken with olive oil and a splash of balsamic vinegar, plus salt and pepper. Once the chicken is cooked through, remove from the oven and top with a spoonful of roasted spinach and tomatoes and top with mozzarella cheese.
Place chicken back in the oven until the cheese is nice and melty!
