Take 1 sheet Puff pastry out of the fridge for 15 minutes before rolling out.
Preheat your oven to 220°C/200°C(fan)/425°F/Gas 7.
Run a knife round the edge of the pastry, to make a 1 inch boarder. Add half the 50 g Mozzarella and half of the 50 g Mature cheddar to the pastry, keeping it inside the boarder.
Add 1 Beef tomato and 6 Cherry tomatoes.
Add the rest of the cheese and 1 pinch Sea salt and ground black pepper.
Put into the oven for 25 minutes, until golden.
Top with Rocket (arugula) and Balsamic glaze if using.
Notes
Add pesto in between the tomatoes before putting the second lot of cheese on.
We have used ready made puff pastry to save some time, however you could make your own if you wanted to.
It's important to leave a boarder around the topping, as it puffs up around the tomatoes and cheese.
Brush the boarder with an egg wash if you want it to get extra crispy.
For some extra flavour and saltiness, add some chopped olives.
You could add a couple of spoonfuls of tomato puree on the base with crushed garlic sprinkled over for some extra flavour.
Add a kick of spice by sprinkling some crushed red chilli flakes just before serving.
If you wanted to add some protein to this, you could add cooked shredded chicken or smoked salmon.
