Put the flour, yeast and salt into a mixing bowl and stir together. Use a dough hook attachment for a hand mixer or mixing machine.
Keep the mixer on while pouring in the water and olive oil.
Knead the dough for around five minutes or until it's springy and stretchy. If you're making this by hand kneading will take around 10 minutes.
Put the dough into a large oiled bowl, cover the bowl with a damp tea towel and leave in a warm place to rise for an hour.
After an hour, knock the dough back.
Lightly oil a large baking tray (one that has low sides). Stretch the dough to fit the baking tray taking it right up to the sides.
Leave the dough to rise for 30 minutes. After this it is ready to use as below.
To make the sauce
Get a small saucepan onto a medium low heat and add the onion and nduja. Fry everything together for 10 minutes breaking the nduja with a spoon.
Add the fennel seeds to the nduja and fry for a minute more.
Add the tomatoes and thyme. Rinse the tin out with a little water and add this to the pan too. Leave to simmer for 15-20 minutes, stirring occasionally, until nicely thickened.
To make the pizza
Preheat an oven to 220C.
Bring a small pan of salted water to the boil and add the broccoli. Boil for two minutes then drain well.
Take 2-3 tbsp of the nduja sauce and spread it over the base of the pizza. (See Top Tips above).
Sprinkle over the mozzarella getting it right up to the edges. Put the broccoli on top and then bake in the top of the oven for 10-15 minutes or until golden brown and the base is crispy.
Notes
* I have based my pizza dough recipe on one from Olive which I have made so many times and slightly tweaked it to suit my cooking.I make my pizza dough in a mixer but you can make it by hand.
