Slow roast leg of lamb with chardonnay, rosemary, sage and bay recipe

Now, this is a slow cook but very fast prep dish. I made this at home one Sunday and literally just lobbed all the ingredients in the pan and left it to cook for ages. I was not expecting anything amazing, just a bit of lamb for dinner. But when I tasted it, still on the kitchen counter, I almost ate the whole darn lot myself and did that little dance people do when something tastes really good.
