Watercress and tomato scone-based ‘pizza’

Method

1. Heat the oven to 220°C/200°C fan/gas 7. Put the flour, baking powder and mustard in a large mixing bowl. Add a large pinch of salt and the butter, then use your fingertips to rub in the butter to give a breadcrumb consistency.
2. Using a round-bladed table knife, stir in the watercress and most of the cheese, then make a well in the centre and pour in the milk. Use the knife to mix briefly to make a soft dough. Lightly flour the work surface, then tip out the dough and lightly knead a few times until smooth. Roll out to 1cm thick, then transfer to a baking sheet lined with non-stick baking paper.
3. Bake for 10 minutes, then sprinkle the top with the remaining grated cheese
   and bake for a further 5 minutes.
4. Meanwhile in a mixing/salad bowl toss the tomatoes, peppers, garlic, olive oil, lemon/vinegar and plenty of seasoning. Serve spooned over the top of the cooked scone base, then scatter with the pine nuts and a few extra watercress leaves.
