Slow Cooker "Roast" Shoulder of Lamb

I got a huge shoulder of lamb from Sainsburys, over £22 worth reduced to £6.  Was waiting for a special Sunday lunch with my mum and in-laws.   Having defrosted it I found out my in-laws hadn't written it down and couldn't come, but had to cook it anyway.

I covered it with olive oil and seasoned.  Put little slits all over and filled them with whole garlic cloves and sprigs of rosemary.
I put it in the slow cooker at midnight, and was woken to the most wonderful smells A.M.A.Z.I.N.G..........
It just fell apart and so moist and tender and flavoursome, very much reminded me of Crete  *sighs*.........

Will do this again :)
