Citrus Pork with Barbecued Fruit and Veg

I thought I was following a recipe here but can't find it at all - must have been drunk at the time. Turned out pretty darn good so here it is.

Get a hunk of pork (suspect ours was some part of leg from the huge bone in there but don't actually know) and pressure-cook it generously with a fair deal of orange juice, some wine, seasoning, thyme and bay, and zest and flesh of an orange and a lemon. While that's doing, put some peeled, cubed and seasoned bits of sweet potato on the barbie and start them off. Also, peel and segment some apples, toss in lime juice, skewer, and sprinkle with sugar. When the time is right, put these on the barie too.

When the pork is cooked very nicely, remove the meat and set aside. Strain the remaining sauce through a sieve and proceed to boil down like there's no tomorrow. While you're doing this, trim the cooked pork of any excess skin/fat and put it  on the barbie together with the other stuff to crisp up nicley. Meanwhile, put in a load of pak choi in to boil (it only takes a short while).

Serve drizzled in the reduced sauce - it's really tangy and tasty.
