Horseshoe said:"garlic, olive oil, and chickweed"... Wow, some of the best good stuff you can eat.
A lot of people talk about eating chickweed... and whenever I've tasted it... One taste has been enuff.
If you discover a magic way of prep... that renders it edible... I'd totally give it a shot... there's an abundance of it hereabouts, and tilling it under simply increases it...
So far... the only moderately successful tactic... is to pull it carefully and get the entire root system... and then mulch with an inch or 2 of woodchips...
While you're at it... find a recipe for bittercress... Took a bite of that recently... upset my stomach... very similar to arugula... which I dislike...
