An apparatus for cooking ground beef hamburgers by reflecting and trapping thermal energy and simultaneous accelerated bun cooking. The apparatus comprised of a plate that is hinged to the sidewall of the griddle for the simultaneous cooking of both sides of ground beef and buns on both sides. Once meat is placed in a first cooking area, the plates on the hinge are rotated down and come to rest on the meat, applying slight pressure to the meat. Plates are attached to the side wall and to the rear wall. Modified plates are used to facilitate the rotation of a large wire frame that contains a metal chain mail fabric into a second cooking area. When buns are placed in the second cooking area, the chain mail frame is brought down onto the outer sides of the buns, putting weight on the buns and accelerating their cooking time.
