A multi-use construct (144; 242), comprising: a base (102; 202; 302) including microwave energy interactive material (140; 238; 338), wherein the microwave energy interactive material is operative for converting microwave energy into heat; and a plurality of walls (120, 126; 216, 224; 424) defining an interior space adjacent to the base (102; 202; 302), wherein the base includes a line of disruption (106; 206) that defines a removable portion (104; 204) of the base, the line of disruption being substantially circular in shape and distal from the walls, and a peripheral portion of the base extending from the line of disruption (106; 206) to the walls (120, 126; 216, 224; 424), and the construct is for being transitioned between a first configuration with the walls (120, 126; 216, 224; 424) extending upwardly from the base (102; 202; 302), so that the construct is for containing a food item within the interior space with the food item at least partially seated on the removable portion (104; 204) and the peripheral portion of the base, and a second configuration with the removable portion (104; 204) separated from the base (102; 202; 302), so that the removable portion (104; 204) is for underlying the food item, and with the walls extending downwardly from the base (102; 202), so that the peripheral portion of the base (102; 202; 302) is for overlying the food item. a base (102; 202; 302) including microwave energy interactive material (140; 238; 338), wherein the microwave energy interactive material is operative for converting microwave energy into heat; and a plurality of walls (120, 126; 216, 224; 424) defining an interior space adjacent to the base (102; 202; 302), wherein the base includes a line of disruption (106; 206) that defines a removable portion (104; 204) of the base, the line of disruption being substantially circular in shape and distal from the walls, and a peripheral portion of the base extending from the line of disruption (106; 206) to the walls (120, 126; 216, 224; 424), and the construct is for being transitioned between a first configuration with the walls (120, 126; 216, 224; 424) extending upwardly from the base (102; 202; 302), so that the construct is for containing a food item within the interior space with the food item at least partially seated on the removable portion (104; 204) and the peripheral portion of the base, and a second configuration with the removable portion (104; 204) separated from the base (102; 202; 302), so that the removable portion (104; 204) is for underlying the food item, and with the walls extending downwardly from the base (102; 202), so that the peripheral portion of the base (102; 202; 302) is for overlying the food item. the base includes a line of disruption (106; 206) that defines a removable portion (104; 204) of the base, the line of disruption being substantially circular in shape and distal from the walls, and a peripheral portion of the base extending from the line of disruption (106; 206) to the walls (120, 126; 216, 224; 424), and a removable portion (104; 204) of the base, the line of disruption being substantially circular in shape and distal from the walls, and a peripheral portion of the base extending from the line of disruption (106; 206) to the walls (120, 126; 216, 224; 424), and the construct is for being transitioned between a first configuration with the walls (120, 126; 216, 224; 424) extending upwardly from the base (102; 202; 302), so that the construct is for containing a food item within the interior space with the food item at least partially seated on the removable portion (104; 204) and the peripheral portion of the base, and a second configuration with the removable portion (104; 204) separated from the base (102; 202; 302), so that the removable portion (104; 204) is for underlying the food item, and with the walls extending downwardly from the base (102; 202), so that the peripheral portion of the base (102; 202; 302) is for overlying the food item. a first configuration with the walls (120, 126; 216, 224; 424) extending upwardly from the base (102; 202; 302), so that the construct is for containing a food item within the interior space with the food item at least partially seated on the removable portion (104; 204) and the peripheral portion of the base, and a second configuration with the removable portion (104; 204) separated from the base (102; 202; 302), so that the removable portion (104; 204) is for underlying the food item, and with the walls extending downwardly from the base (102; 202), so that the peripheral portion of the base (102; 202; 302) is for overlying the food item.
