If you're making your own pesto, simply blitz the basil, pine nuts, parmesan cheese, garlic, salt and pepper in a food processor until fine
Pour in a few tablespoons of oil to get the consistency you want - I keep mine quite stiff!
Heat the oven to 220ºC/200ºC fan and line baking trays with parchment paper.
If using ready made puff pastry, simply roll out to the thickness of a £1 coin
Spread your pesto evenly on to the pastry
Spread both the grated parmesan and cheddar over your pesto layer.
You can either cut them into 1cm (1-1.5cm) strips now, or you can fold the pastry over so it’s half the size, then roll it back out to its original £1 thickness, to then cut into 1cm strips. (This will keep more of the pesto & cheese on the inside - but either way is delicious!)
Once the pastry has been cut into strips, simply twist all pieces a few times (the more the merrier)
Scatter over more cheese and bake for 12 minutes (or until nice and golden).
Notes
Pesto is so easy to make at home, and it makes it so much nicer when you know exactly whats in it!
You can use any shop bought pesto instead, if you wish.
