While visiting Mexico as a teenager, I found this rich and comforting soup to be plentiful and delicious in the tourist area at least. Not sure exactly how traditional it is, but it is very quick and simple to put together and loaded with tomato flavor and toasted, nutty pasta. If you wish to skip pureeing of fresh vegetables, I don't see why you couldn't substitute with a jar of your favorite salsa. I plan to try that myself next time just to see the difference. Hope you enjoy this recipe.
