Make the Vietnamese dipping sauce. Detailed recipe instructions here. (This can be made days in advance.)
Prepare all your toppings.
Take the banh cuon (rice sheet rolls) out and cut roughly into 3 - 4 cm / 1 - 1.5 in blocks.
Place them on a plate and microwave for 1 minute on high. Check to see if they have softened enough to unravel. Put any blocks that are still hard back into the microwave for a further 30 seconds or until soft. Repeat until all noodles have softened, being careful not to overcook them.
Gently unravel the rice rolls and divide into portions.
To Serve
Warm the Vietnamese dipping sauce in the microwave for 40 seconds or until warm.
Check if the noodles are cold. If yes, put each plate of noodles in the microwave for 30 seconds or until warm.
Add the toppings to each plate of noodles.
Pour 3 - 5 tbsp of Vietnamese dipping sauce over the top.
Serve with extra Vietnamese dipping sauce on the side.
