An oven, comprising:
- inner oven walls defining a cavity within the oven, wherein the oven has a front and a rear;
- a meal carrier positioned within the cavity of the oven, the meal carrier having a front and a rear corresponding to the front and the rear of the oven, respectively, the meal carrier including a top wall, two side walls, and a bottom wall, the front and the rear of the meal carrier being open to allow a flow of air through the meal carrier from the rear of the oven to the front of the oven, the meal carrier including a plurality of meal trays positioned generally parallel to the top wall and the bottom wall of the meal carrier;
- at least one heating element configured to heat air in the oven, the at least one heating element positioned between the meal carrier and the rear of the oven;
- and
- at least one fan positioned between the rear of the oven and the at least one heating element, the at least one fan configured to:
