Start by heating your wok over high heat. While it's heating, pass your banana leaves quickly over an open flame until shiny and pliable, then set aside.
Once your wok is hot and lightly smoking, add one tablespoon of oil. Add the sliced pork belly and cook until golden brown, about 3-4 minutes.
Lower the heat to medium, then add minced garlic and chopped onions. Cook for 2 minutes until the onions become clear and fragrant.
Turn the heat back to high. Add your carrots, chayote, and pork liver. Cook for exactly 1 minute – you want the vegetables still crisp and the liver just cooked. Remove everything from the wok and set aside.
Pour 3 cups of stock and soy sauce into the same wok. Let it come to a strong boil. Add your Lucban miki or Shanghai noodles and cook for 5 minutes, stirring now and then so they don't stick. If the noodles look dry, add more stock – you want them moist but not swimming in liquid.
Put the cooked meat and vegetables back in the wok and mix everything well. Season with fish sauce to taste and add fresh ground black pepper. The noodles should still have a nice bite to them.
To serve, shape a banana leaf into a half-tube. Put a portion of the hot pancit on the leaf and serve right away with calamansi halves on the side.
Show your guests how to eat it the traditional way: lift one end of the banana leaf near your mouth and gently slide the noodles in. Keep some napkins nearby – it might take a bit of practice to get it right.
The whole dish takes about 30 minutes to make. Eat it right away while it's hot and you can still smell the nice aroma from the banana leaves.
Remember: the trick to great Pancit Habhab is keeping your vegetables crisp, your noodles just right, and your banana leaf properly heated. If you manage these three things, you'll have a perfect plate-free pancit every time.
