Preheat the oven to 200C/400F degrees

Mix the coconut flour, salt, baking powder and psyllium husk powder together.

Add the coconut oil and blend well.

Add the egg and mix thoroughly.

Add the boiling water and mix until you have a dough.

Let stand for 30 minutes.

Place the broccoli in a saucepan of water. Bring to the boil, cover and simmer for 10 minutes.

Drain and mash with a fork. Season with the salt and pepper.

Place the dough on a large piece of parchment paper.

Place another piece of parchment paper on top of the dough and roll out into a rectangle.

Spread the broccoli over the dough and then scatter over the blue cheese.

Using the parchment paper at the bottom, gently roll the dough length-wise so you have a large swiss roll.

Seal the ends and brush with the beaten egg

Bake for 20-25 minutes until golden and firm.
