Wrap food in cylinder shape and put in the fridge
This is called a roulade. It is when a protein or vegetable is rolled, typically in plastic, very tightly.  It is sometimes also tied. The roulade, can be poached or cooked sous vide in the wrapping, if it is to be a hot preparation.  It can also be refrigerated for cold preparations.  The cooking, or refrigeration, help keep the roll in tact when slicing for service.  A modernist technique for maintaining the roll might be to use transglutaminase (otherwise known as "meat glue").
