1 sheet/block of puff pastry rolled out
Tomato puree/passata/ something like that
Spread the tomato-y stuff on the pastry but leave about 2cm round the edge (this will puff up bigger and make the tart shape).
Sprinkle on the cheese (I used mozerella and cheddar) and ham
Bake (at about 220 degrees celsius) for 15-20 min. Eat. Enjoy
My mozerella was sloppy and it made the base a bit soggy. Still edible though. Might have some beans on toast later too. I'm having a hungry day (week, month, year....)
