coincidentally, uncrustables were my hyper fixation for a good minute a few years back, but i just liked em cold. Didn't cross my mind to toast it but i dont think i would have if it did.
i might go for it one day....after I try butter on a pop tart. i eat a lot of those but cant bring myself to put butter on it....damn, i don't toast those either....I just realized i dont like toasted stuff i think
