Stupidly Simple but Surprisingly Scrumptious Soup

HH and I just wrapped up dinner -- it was a Chicken Tortilla Soup from my Williams Sonoma Food Made Fast "Soup" book. I kept looking at the recipe to make sure I wasn't missing something! And you know what? We loved it. Granted, we fancied it up with homemade tortilla chips that HH made while I cooked everything else. But still...

Chicken-Tortilla Soup

6 c. chicken stock
2 c shredded, cooked chicken
(lil' secret -- I used the rest of a Costco rotisserie chicken for both of these. We'd eaten off of the breasts for a few days, so I used all the dark meat -- has more flavor anyway -- that I pulled off the bones and shredded, and it was almost exactly 2 cups. Then I made chicken stock out of the carcass -- just put it in the crockpot with veggies, herbs and water and let it simmer for a couple of hours. I love a) how cheap it is, and b) how much flavor it has. But I digress...)

1 T. olive oil
1/2 white onion, finely chopped (I used a whole onion)
2 tsp chili powder (I used 1/2 tsp chipotle chili powder and 1 1/2 tsp regular -- it added more spice and a little bit of a smoky flavor, but it would still be great with only regular)
lime juice (3-4 limes)
salt
corn tortilla chips
1/2 c. queso fresco or shredded monterrey jack cheese
avocado
fresh cilantro

1. In a large saucepan over medium-high heat, warm the oil. When it is hot, add the onion and saute until translucent, about 3 minutes. Add the chili powder and stir until fragrant, about 1 minute. Pour in the stock and bring to a boil.

2. Add the shredded chicken, reduce the heat to medium and simmer until the chicken is heated through, about 3 minutes. Add the lime juice and salt to taste. Ladle into bowls, garnish with the tortilla chips, queso fresco, avocado and cilantro.

Seriously? Onion, chili powder, chicken stock and chicken, with lime juice and tortilla chips on the side. Can dinner get any more simple while still being delicious?

Oh, and I didn't have any avocado or cilantro, so instead we garnished it with tomatoes and green onions (and pepper jack cheese). I didn't add the lime juice while it was cooking; we just had lime slices that we could squeeze over our soup.
