A dinner roll is a small, individually portioned yeast bread, usually round or oblong, served as a side with a meal. It's made from the same basic ingredients as most yeasted breads - wheat flour, water, yeast, and salt - often enriched with butter, eggs, or milk for a softer, richer crumb than a plain crusty loaf.
Dinner rolls accompany a wide range of main courses, from roasted meats and stews to soups and salads, and are a fixture of holiday meals like Thanksgiving in the United States. They're mild and slightly sweet, with a soft interior and a light crust, and pair well with butter, honey, jam, and cheese; smaller rolls are often used for sliders or mini sandwiches.
