Don't have a top 10, but it's not rare for me to devour a whole tub of pringles in one sitting, most flavours really. Also, the salt and shake crisps, can eat all 6 packs in one sitting, WITHOUT the salt added. I love them plain.
And those savoury cheese twist/sticks things.
However, i never go shopping hungry now, which definitely helps when trying to avoid over buying junk food. That's not to say i don't sneak in a tub of pringles here and there though
