Heat the oil in a frying pan, then add
the onion and garlic and cook for 5 mins.
Tip in tomatoes and passata, and simmer
for 5-10 mins or until the tomatoes are
soft. Remove from the heat, stir in the
basil, season, then allow to cool.
Put the flour into a bowl. Make a well
in the centre, add the olive oil then add
6-7 tbsp warm water or enough to
make a soft dough. Tip the dough onto
a lightly floured surface and roll out to
fit a 22cm frying pan or make 2 small
ones. Heat a glug of olive oil in the
frying pan, then press the dough into
the pan and cook over a medium heat
for 8-10 mins or until the base is golden.
Heat grill to hot. Spread the pizza
base with the tomato sauce, scatter on
the cheese and grill until it has melted
and the base is golden at the edges.
