Pasta with Grilled Chicken+Mozzaralla

On my search for healthy recipes I came across this one and it sounded delicious, but I was very skeptical about trying as its main component is pasta, which is a carb and I am very anti-carb, but I tried it any way and it was deeliciouus! Soo here is my slightly adjusted version:
