Vegetarian Tortilla Soup

This soup may be the most customizable meal ever. The base is vegan and with a variety of toppings, you can make it whatever you want. Great for a dinner party. In fact, it debuted at the inaugural meeting of the Order of the Purple Finch.  Serves 8.

Base:
1 large onion
4-6 cloves garlic
1 red pepper, seeded and roughly chopped
1 poblano, seeded and roughly chopped
2 carrots, peeled and chopped
1 1/2+ cups fresh tomatoes (or frozen roasted tomatoes, or 1 14-oz can of tomatoes)
1 can of tomato paste
6 cups of veggie broth
1 t. cumin
2 t. ground coriander
cayenne, spicy paprika, or New Mexican red pepper to taste (I used 1 t. New Mexican)
olive oil
salt to taste

In dutch oven, sautee onion and garlic until fairly soft. Add spices. Add peppers and carrots. Sautee 5-10 minutes. Add tomatoes, paste, and broth. Simmer until all ingredients are very soft. Add more water or broth as necessary. Remove from heat. Puree using immersion blender. Adjust to your desired thick/thin-ness. Adjust seasoning and salt to taste.

Now, here's the good part. Ladle, steaming hot, into bowls over crushed corn tortilla chips (NOT Tostitos or some crappy fake chips, use the real thing) or strips of corn tortilla, oven toasted with a little oil. Let people top the soup with things like:

oven-roasted corn
oven-roasted grape or cherry tomatoes
diced white onion or scallions
finely chopped radishes
black beans
chopped cilantro
avocado or guacamole
limes, quartered for squeezing
chopped hard boiled egg
sour cream
cheese: chihuahua, goat, or jack
sauteed tofu or seitan

Try to have the toppings (other than the sour cream) at room temp so they don't cool the soup too much.
