My go-to is pressed pork belly, mustard mash, vegetables and honey, soy and hoisin jus. Sounds tricky - really isn't! It's great because you can prepare in advance and has a short cooking time on the day. Sauce can be done in advance. Looks dead fancy.
Copy and pasted method below in case you're interested!
Slow roast (skin on, skin up, boneless belly) in the oven for 4-5 hours on low on top of onion, celery, carrots, orange juice, 500ml stock, star anise. Salt skin. Cover with foil. Don't get skin wet.
Take out and drain juice - retain for sauce.
Put pork into a container with a flat bottom. Cover with baking paper and something flat on top. Press with heavy weights/tins..
Refrigerate overnight. Slice up next day into squares. Squares can then be pan fried or placed into hot oven to crisp skin (20mins cooking time).
Reheat sauce. Add dash of soy, 2tbsp honey half jar or hoisin. Reduce till thick and glossy.
