Let's continue this awesome 'bacon' theme this week, shall we?
It seems most 'bacon' flavored foods are really just the salty, smokey flavored foods... hinting bacon. The reviews of this product seem to be "smokey, salty" popcorn or "popcorn with bacon flavored salt on it". Either way, it sounds like something I'd like to try.
Now, this particular link (above) says it's Vegetarian safe - obviously, since there is no real bacon in the popcorn salt. So... there ya go!
