There's a lot going on in these things: juicy layers of chili-lemongrass bombed chicken, nice and tender with charred aromas (like satay); a bonus addition of well-seasoned egg omelette; some chicken floss; & the smattering of crunchy, punchy pickled vegetables all in a loaf of bread that's totally unique in its construction. It seems like we can be on our way to a very substantial meal with them.
& As much as I love eating banh mi, I always prefer to leave the actual making of them to the professionals, like the ones here from @NamNamNoodleBar. What's your favourite?
