Okay, u'pastizz 'rtunnar is a phrase in Maltese that means "turned pastries". So imagine you are in a bakery or in your kitchen and you have some dough that you want to turn into pastries. You can make different shapes and fill them with yummy things like cheese or peas, for example. The process of turning the dough into these yummy pastries can be called pastizz 'rtunnar. It's like when you play with playdough and you squish it and shape it into different things, but with dough that you can eat!
