When I first encountered banh pho dried rice noodles -- the noodles often sold as pad Thai noodles, or rice vermicelli -- I thought they were, well... astonishing. After a brief soak in a bowl of warm water, these brittle, opaque noodles got tossed directly into a wok -- no boiling, can you imagine? -- where the heat softened them to chewy perfection in just a minute or two. Wow. Everything, sauce and noodles, cooked in the same pot, and that made a believer out of me. The noodles have no real flavor of their own, and happily soak up any sauce and spices that surround them. This recipe is a template for all kinds of rice noodle stir-fry dishes. Swap turkey, chicken or pork for the beef; add snow peas or bok choy, or any vegetables you have on hand. Banh pho keeps in the pantry cupboard for a year or more, and offers a easy, inexpensive, gluten-free alternative to wheat noodles.
