A first heat source is positioned to direct heat energy into the first toasting zone. A second heat source is positioned to direct heat energy into the second toasting zone. The first and second conveyors are coplanar and laterally spaced apart by a first distance and are configured to operate in a same direction of travel. Interior extents of the first heat source and the second heat source are laterally spaced apart by a second distance. ## Claims ### Claim 1 A toaster for toasting a bread product comprising: a first conveyor configured to receive the bread product thereon and move the bread product through a first toasting zone;
