Sticky onion & sausage pizza

Method

• step 1

  Tip the bread mix into a large bowl. Make a well in the centre and pour in 1 tbsp olive oil and 350ml tepid water. Mix to form a dough, then turn out onto a lightly floured surface and knead for 5 mins. Transfer to a lightly oiled bowl, cover and leave to rise for 30 mins.

• step 2

  To make the topping, heat the remaining oil in a frying pan and add the onions, rosemary and a good pinch of salt. Cook gently, stirring occasionally, for 25-30 mins until starting to caramelise. Boil the kettle. Put the spinach in a colander and pour over the boiling water. Leave to drain and cool, then squeeze as much liquid from the spinach as you can and season. Squeeze the sausages from their skins into a small bowl and stir through the mustard. When the onions are softened, pour over the balsamic vinegar and stir well. Cook until almost all the vinegar has evaporated and the onions are sticky.

• step 3

  Heat oven to 220C/200C fan/gas 7 and pop in 2 baking trays. Tip the dough out and divide into 2 equal pieces – do not knock the dough back or it won’t hold its shape. Stretch and roll the dough into 2 large circles, about 30cm diameter. Transfer the bases to the trays. Spread over the onions, top with the spinach and cheddar, then dot over the mustardy sausage. Bake for 15-20 mins until crisp, golden and the cheese is bubbling.
