Good for you Kaye….it is probably better for them as wild greens are often packed full of vitamins & minerals etc. I often eat so-called weeds, as long as I can be fairly sure no dogs or cats have peed or pooped on them…… I always wash them in plenty of water & put some vinegar in the final rinse. My grandmother always gave us wild greens every spring…..she called it Spring Tonic. My grandfather had a large allotment so there was always a good selection of his veg all the year round but she always insisted that we had our share of wild stuff….she disguised it sometimes by chopping finely & adding to mashed potatoes. This is great with young dandelion leaves, chopped & bits of crispy fried bacon, using the bacon fat instead of the usual butter, at the last moment add a tiny sprinkle of cider vinegar. It is my British version of a dish I use to eat in Holland, using frizzy endive (chicory).   

Kaye I think you would have to marinate it for a longish time in something very powerful.  Personally I would try fresh pineapple (they are cheap at the moment), garlic, vinegar herbs etc. You could try salting & pickling it , ending up with a real version of corned beef.
