This is a delicious, hot tomato soup with melty cheese and softened tortilla chips. It's great with limes!
I based this recipe on the following: http://www.simplyrecipes.com/recipes/tortilla_soup/, but since frying the tortillas seemed a bit of a pain, I used tortilla chips.
If you like it spicier, add sliced jalapeno.
Enjoy Japanese food around the world.
