I feel fortunate that I live in an area where I have easy access to such a rich variety of food. Check out these beauties (Vietnamese fried imperial rolls on the left and summer rolls on the right - both vegetarian):
They're stuffed with tofu and all sorts of wonderful veggies (jicama, carrots, etc.). Totally portable, healthy and nutritious (well, minus the little frying part for the imperial rolls). Now this is "fast food" I could have every single day.
