This recipe shares a method for making Vietnamese Savory Crepes (Banh Xeo) from scratch, without relying on a premix flour bag. These crispy crepes are traditionally served with an array of fresh vegetables like lettuce, a Vietnamese herb mix, cucumbers, and a side of Vietnamese Sweet Fish Sauce Dressing (Nuoc Cham). The recipe provides instructions for the batter and the cooking process, though specific ingredients for the 'proteins and onion' filling are not detailed.
