Tender Slow Roast Pork on bed of vegetables

I know I have covered roast pork before, but this turned out wonderfully, so I thought I would shove down the recipe on the site before I forgot how it went.
Roasting anything in a baster is rarely going to go wrong. This is a shoulder roasted in a baster on a bed of vegetables - the vegis acting like a trivet as well as adding to the flavour.
