'Ryouri suru' as a verb can mean to things: 'to cook' and 'to handle, to manage'. 'Ryouri shite' is a certain conjugation of that verb called 'te-form' which is used to show a sentence is not finished and is somehow connected to what we want to say next. E.g. 'Sakana wo Ryouri shite, tabeta' => 'We cooked the fish and ate it.'
The same is true if it is used in sense of 'dealing with, managing'.
