It’s Vietnamese. Banh Mi is a Vietnamese sandwich traditionally made with a wheat/rice flour baguette, so it’s totally in keeping with a rice flour baguette. 
Banh Mi can have a lot of different ingredients like pulled pork, chicken, and pate, in addition to cucumbers and cilantro. Although Banh Mi is also sometimes also made with pickled daikon, it’s much easier if you just use homemade pickled carrots, which are pretty good on their own.
Ingredients:
For the pickled carrots:
