I’m not sure what this is, but I had this amazing dish in one of the most depressing shopping malls on planet Earth, near Cupertino, CA, and then again at a great pho place in Mountain View. (Correction: it’s called bun, and I’m ignorant.) The basic idea is lettuce, mint, rice noodles, and something savory, like a chopped egg roll, shaved pork, or chicken or something.
