Low cal Tomato Tortilla Soup

I saw this on a website and thought I'd try it tonight. So good! I changed a couple things, though. Instead of sauteing in oil, I just used some chicken stock (it's a great saute substitute!), and I also added some Chipotle Chili Powder that I just got. Added a great smokey flavor! Counts are below. Makes 4 good sized servings. Hope someone else tries and likes it!

2 garlic cloves, finely chopped
1 medium onion, coarsley chopped
1 tsp crushed red pepper flakes
4 cups chicken broth (I used low sodium chicken broth but couldn't find it when I calculated the information so the sodium count is for using a full sodium one)
One 28 ounce can diced or whole tomatoes
1 tsp ground cumin
Juice of 1/2 lime
5 6-inch corn tortillas, torn into small pieces

In a large pot, add onion, garlic, red pepper flakes, and a few tablespoons chicken stock. Saute over medium heat until the onion is translucent. Add the remaining chicken broth, tomatoes with juice, cumin, and lime juice. Bring to a boil and let simmer 10 minutes. Add tortillas and simmer another 5 minutes, until tortillas begin to fall apart easily. Puree soup either in a blender or food processor in batches or using an immersion blender (fantastic kitchen tool!). That's it!
