Line a baking tin / baking sheet with baking paper.
Spread the tomato puree evenly over the puff pastry sheet.
Sprinkle the grated cheese over the tomato puree in an even layer.
Taking one edge of the puff pastry, roll it up into a tight log. Cover with cling film and place into the fridge for 15 minute to chill (optional).
Using a sharp knife, slice into 1 cm (⅓ inch) thick slices.
Place the pinwheels on to the lined tray, leaving room in between them, and place in the preheated oven. Bake for 15-18 minutes, until golden.
Cool slightly on the tray before serving.
Serve warm or at room temperature. Can store in the fridge, covered, for up to 3 days, or freeze.
Notes
INGREDIENTS
Puff Pastry – here in Australia I use sheets of frozen puff pastry which weigh 160g (5.5 oz) each. If you are in the UK, a sheet often weighs 320g so will make double the amount of pinwheels, or cut the pastry in half. If you buy blocks of puff pastry then use 160g puff pastry and roll out to a square that is approx. 25cm x 25 cm (9.8″ x 9.8″)
Tomato paste – also known as tomato puree – this gives a tomato flavour without adding much liquid, which can result in soggy pinwheels.
Cheese – I often block mild cheddar cheese or tasty cheese, if you have a strong cheddar that would also be lovely.
TIPS
Adding vegetables – sprinkle half a small finely chopped red pepper / capsicum over the cheese before rolling up.
If the pastry is warm – place the rolled pinwheels in the fridge, covered to prevent them from drying out, for 15 minutes. This will allow you to slice it neatly.
