Giant sausage roll

Step 1

Heat the oven to 200°C/180°C fan/gas Heat a pan with a glug of olive oil and fry the fennel seeds for a minute.

Step 2

Add the chopped onion and mushrooms, then fry for 10 minutes on a high heat, stirring until browned. Tip into a large bowl with a bunch of chopped fresh dill and the sausagemeat. Season and mix to combine.

Step 3

Unroll the ready-rolled puff pastry onto a board. Put the sausagemeat lengthways down the middle of the pastry, then cut the pastry into strips, at right angles to the sausagemeat, all the way down. Cross the strips in a lattice over the sausagemeat to cover it. Transfer the plait to a baking sheet lined with non-stick baking paper, brush with the beaten egg, then bake for 30-35 minutes.
