Flour an oven dish, I used a very rectangle tray that we use for making oven chips. Roll out the puff pastry to fit the tray.

Dab tomato puree along the pastry and use a knife to smooth it out across the whole base.

Sprinkle on the chicken evenly, spread the cherry tomatoes out and top it with the cheddar cheese.

Bake in the oven at 200 Degrees or 180 Degrees for a fan oven, for up to 20 minutes.
