I do slow cooked pulled pork with crackling, which does us for two main meals.
Buy a large 2-3kg boned and rolled pork shoulder
Dry the skin with kitchen roll and score it
Rub in lots of salt
Very high heat for 30 mins until skin looks fairly well crackled
Turn down to really low heat
Cover with foil and cook for 4-5 hrs
Remove foil, drain fat/juices for gravy
Give it a final hot blast for 20-30 mins to finish off the crackling.
It comes out perfectly with meat that falls apart, the fat melted away, and really crunchy crackling.
Meal 1 is the plain pork with crackling, gravy, apple sauce, red cabbage etc.
Meal 2 is BBQ pulled pork, wraps, homemade coleslaw and salad (made by reheating leftover pork with a bottle of posh BBQ sauce, then pull apart with forks)
There's usually enough for a third day of sandwiches too.
You could freeze the leftover meat after meal 1 so you're not having pork three days running.
