Include Vegans

My husband and I wanted the Wacky Wednesday combo with Mushroom burgers as we are Vegan and are so impressed that there is another vegan option. However the mushroom burger is NOT included in the Wacky Wednesday combo for unknown reasons. It is cheaper than chicken and beef yet people can choose those options? Please Steers, make the mushroom burger an option for the special too because the other veggie burger is cardboard. Thank you
