Preheat oven to 190 degrees
Dice up your chicken, onion and peppers
Add all of your ingredients apart from the mozzarella into a large ovenproof dish. Rinse out the tin of chopped tomatoes with 100ml of water and pour in. Mix thoroughly
Top each with 80g of mozzarella, cover with tin foil and bake in the oven for 50 mins at 190 degrees (45 mins covered and the last 5 uncovered)
Leave to rest for 5-10 mins after cooking so all the water is soaked up
Serve and enjoy
