1. An under-fired grill comprising:
a grate formed with a plurality of metal burner shields each having a curved top support surface and two downward extending legs, wherein food is placed directly on the grate formed by a plurality of top support surfaces of the burner shields for cooking;
an integrated burner formed within each burner shield below the top support surface, such that the burner is positioned entirely below the top support surface and entirely above distal ends of the two downward extending legs and generally centered therebetween;
wherein each burner shield is formed of a solid sheet of metal with no openings within either of the two downward extending legs, and the integrated burner is disposed closer to the top support surface than to the distal ends of the two downward extending legs, whereby each burner heats the top support surface of a corresponding burner shield for conduction heat transfer and radiant heat transfer, and convection heat moves within each burner shield down the two downward extending legs and around the distal ends of the two downward extending legs to transfer heat to the food through convection heat transfer.
