As much as I'd love to see this, SE won't put event food furnishings on the salvager because they'd lose out on those cashshop sales. I still think the easiest option would just be to add a food toggle to the FC/Housing permissions. This way, if you want the "clean" plate look you can just turn off the seting until the food is used up. Either way, I feel like something seriously needs to be done about this. It really ruins the fun of decorating.
