The speed and deliciousness balance can't be beat when it comes to banh mi. A quick 2 minute stop at a sandwich stand leaves you with a fresh baguette filled with cha lua (Vietnam's version of ham), cilantro, pickled carrot and daikon, chili pepper, hot sauce, pork fat, and maybe some pate.
Chả Lụa is a thing of beauty. In English it's sometimes refered to as pork roll, or pork loaf. In Vietnamese it's also called giò lụa. It's basically a mixture of ground pork, herbs, and spices that are wrapped in a banana leaf and steamed. Make sure you try multiple banh mi stands before you settle on being a regular at one. The cha lua is often homemade and different stands will have a different variety of spices.
