I agree, if you are good at ID, look for it and taste first.
A park near here has had a 'pull GM" event and cook, I think they posted cooking some to add to a potluck after, I never attended.
Of the wild 'edibles' I have tried, most teach me the difference between 'edible' and 'tasty.' Or at least, you'll have to acquire a taste. The same amunt of effort could be more satisfying with some known crop.
But hey, curiosity..
