Well I dont know about where you live, but the fields here are full of stinging nettles just stinging to be picked to be made into a yummie healthy soup!
Let me know if you want the recipe & tips on how to pick it. It is so easy & delicious!
Did you know it contains lots of protein (40% of dry weight)? That is more than soya has! What a great choice for vegetarians. It is free and probably somewhere near your toes everytime you step outside!
