i've got a packet of the pepperjack ones in my fridge.
i bought them home from the supermarket all excitedly, then took one out, unwrapped it, peeled a sliver the size of a fingernail off the edge of the slice, tried it, and nearly gagged.....
it's gritty, waxy, greasy, slimy, and tastes foul to me.
that said... i threw the rest of the slice out, and didn't get as far as trying melting it, so it might have tasted better melted. and i'd never had pepperjack cheese (vegan or not) before either, so maybe i didn't like the pepperjack-ness of it either, which may have added to my dislike of it somewhat.
i've been planning to feed the rest of the pack to my human dustbin of an omni bf, but maybe i'll give it another shot myself first... i doubt it though... my memory of the tasting event consists of pretty much the words 'bleurgh bleurgh, and bleurgh'.
i much prefer the old 'vegan' ones in the purple packets (and then only in a select few meals)... ok, so they don't melt, but they don't feel like a mouthful of greasy sawdust either.
