Pre-heat the oven to 200C/400F degrees.

Mix the dry ingredients in a bowl and combine well.

Add the butter and eggs and mix thoroughly until the mixture looks like breadcrumbs.

Boil the water and add to the mixture a bit at a time, stirring thoroughly until you have a dough.

Cut the dough into four. Take one of the quarters and roll into a ball. Place this on a strip of parchment paper.  Place another strip of parchment paper over the dough ball and roll out into a rectangle about 8 x 4 inches.

In a bowl, mix the broccoli, Cheddar cheese and mustard together, mashing gently with a fork.

Spread the broccoli and cheese mixture over the dough pieces.

Using the parchment paper base, take one end and roll up the dough like a Swiss roll, keeping it fairly tight.

Cut the dough into half, then half again. This will make your pinwheel shape.

Place the pinwheel face down on a parchment paper lined baking tray.

Bake for 20 minutes, turning over after 10 minutes.

Eat and enjoy!
