That casserole was my 2nd favorite part of the episode, topped only by the sister getting fed up with her shit. I love potatoes and it's always crazy seeing just how unhealthy fat people can make them. I mean that same basic taste is pretty easy to get through other means. Obviously not exactly, but I'd guess balasmic roasted potatoes and broccoli with a 'small' bit of cheese would match up pretty well. While being fairly low calorie at the same time.
