This sandwich began with Warburtons [sic] soft grained farmhouse, lightly toasted and scraped.
Then I filled it with:
a generous layer of Sharwood’s mango chutney from a squeezy bottle;
some finely chopped spring onion and celery (cucumber would have been good, but we never have cucumber in);
a generous layer of PDO cheddar, grated.
Then I shoved it in the microwave for a minute, to melt the cheese a little.

Delicious! You do need a strong cheese to make it work.
