Two soups I love - egg drop soup and tortilla soup. Combine them together, and you get Southwestern Egg Drop soup! Nope, not a recipe, just an imagination in my head that I tried to translate into a dish. Let me note two things to start though, 1) I've never made egg drop soup before, and 2) I am not a skilled soup maker in general. Considering this was my first attempt at the recipe-less, hodge podge creation, I'd say it was a good start.
