Tuna, olive & rocket pizzas

Ingredients

 * 145g pack pizza base mix (or same weight of bread mix)
 * 2 tbsp tomato purée
 * 185g can tuna in oil, drained, oil reserved
 * plain flour, for dusting
 * 1 tbsp capers
 * 125g pack value mozzarella
 * 10 pitted black kalamata olives
 * 1 small red onion , halved and thinly sliced
 * small handful rocket

Instructions

 * 1) Heat oven to 240C/220C fan/gas 9. Tip the pizza mix into a bowl and make up following pack instructions. Cover the bowl with a cloth and leave for a few mins.
 * 2) Meanwhile, mix the tomato purée with 4 tbsp water, 1 tbsp oil from the tuna and some seasoning.
 * 3) Knead the dough for a few mins on a floured surface, then halve and put each piece, spaced apart, on a large oiled baking tray. Press with an oiled hand to make thin flat pizzas - they don't have to be perfectly round.
 * 4) Spread with the tomato purée mixture, then top with the tuna, capers, cheese and olives. Bake for 10-12 mins. Serve scattered with the onion and rocket.
