Abstract
A method for heating an edible product enclosed within a pouch. The method includes placing the pouch within a sleeve having a wall extending between an open first end and a second end having a sleeve gusset. The edible product within the pouch is then heated causing the pouch to bulge due to an increase in pressure within the pouch. The bulging pouch pushes against the wall of the sleeve causing the sleeve to bulge and un-fold the sleeve gusset at the second end. The increased pressure within the pouch may also unseal at least one sealed vent on the pouch. Once heated, the pouch is torn open along one or more tear lines, thereby providing access to the edible content of the pouch. In some embodiments, the sleeve is reusable and included in a kit having two or more pouches.
