When I see "ISO," I might not even open the thread unless I feel like I might have a recipe or something else concrete to offer the OP. I also think of it as an S.O.S. shout where the OP is asking for help, and a reply less than helpful is rude, almost like kicking a dying man.
Pac, summer rolls are refreshingly good finger food.
But there's no reason why you can't try making sesame noodles from your pho. The Vietnamese word for noodle, derived from the Chinese "fun," is bun or bahn. And it's usually made from rice flour. It has no gluten. So, after cooking, the noodles can easily break apart. In a soup, it's no big deal since the broken bits are slurped down with the soup. Whereas bits of broken pasta is problematic with a fork or chopsticks. Try firming the pho in the frig for an hour, and then toss with dressing into cold sesame noodle salad.
