Preheat the oven to 190°C
Dice the chicken, onion and peppers
Add pasta, chicken, vegetables, cream cheese, garlic, fajita seasoning, chopped tomatoes, salt and pepper into a large ovenproof dish
Rinse out the chopped tomato tin with 100ml water and pour it into the dish
Mix everything really well so it's evenly coated
Sprinkle the mozzarella evenly over the top
Cover with foil and bake for 45 minutes at 190°C
Remove the foil and bake for another 5 minutes to melt and colour the cheese
Remove from the oven and let it rest for 5 to 10 minutes so the sauce thickens and the pasta soaks everything up
Serve and enjoy
