Ground meat (such as beef, turkey, lamb or pork) mixed with various seasonings (like onions, bell peppers, herbs, ketchup, and so on) and bound (see bind) with eggs or bread-crumbs. The mixture can be either spooned into a loaf pan or hand-formed into a loaf shape and placed in a baking pan before being baked. Meatloaves can be topped with various ingredients such as cheese or sauce, and served both hot and cold.
