My guilty pleasure, when I want to indulge, is vegan chocolate chip cookies from our local organic store, they are made there and are big, soft, full of choc chips and just too yummy to describe. I get them a few times a month for a treat.
My savory guilty pleasure is pizza. I stay away from dairy but once a month or so I get a small veggie pizza with double cheese and devour it! I have to be careful how often I have cheese b/c my body reacts to it, flaring up inflammation and skin problems, but an occasional indulgence is sooo good.
