This is an American-Italian dish that is a pounded beef filet that is stuffed with cheese, herbs, and breadcrumbs that is then pan-seared and braised in a tomato sauce.
Add the tomatoes to a blender and blend on medium speed until smooth. Transfer to a medium-sized pot, season with salt and pepper, and cook on low heat.
Next, slice the sirloin roast into 12 thin fillets and pound each of them out on a cutting board in between plastic wrap or a plastic bag until it is about ¼ thick. Season with salt and pepper.
Add a small amount of the breadcrumb mixture to the center of 1 pounded beef fillet and spread it out across the beef fillet, pressing it down into the beef. Roll up the beef to make a roulade.
