Preheat oven to gas 5/375F/190C.

Place the chicken breasts between two sheets of cling film and bash with a rolling pin to flatten them.

Place on a baking tray and divide the passata between them, coating the whole top of the breasts.

Sprinkle basil on then top with cheese.

Bake for 25-30 minutes, until cheese is golden & bubbling.

Enjoy!
