In a heatproof bowl, cover the noodles with boiling kettle water.
Peel the onion and chop into 1cm chunks, roughly slice the chilli, then dry fry and char both in the hot pan for 2 minutes, stirring regularly.
Trim the pork of any sinew, then chop it into 2cm chunks.
Peel and slice the garlic, stir into the pan with the pork and 1 tablespoon of olive oil and stir-fry for 2 minutes.
Chop the baby corn and mangetout into 2cm lengths, then toss into the pan and stir-fry for another 2 minutes.
Add 1 tablespoon of red wine vinegar and the black bean sauce, let it sizzle for 30 seconds, or until the pork is just cooked through, then season to perfection.
Drain the noodles and divide between your bowls.
Spoon the pork, veg and black bean sauce on top, crumble over the prawn crackers, and tuck in.
