Arrange your entire dinner on a sheet pan, pop it in the oven and - voila! Your complete meal is ready. Sheet pan meals are one of the easiest and fastest ways to make an entire meal. In most recipes you can add or subtract various vegetables at will. There is a lot of room for creativity with these meals. If you don't have a rimmed sheet pan, go ahead and use a 9 x 13-inch pan if the ingredients will fit into it comfortably.
