I love this soup. I make a big batch for dinner and eat the rest for lunch the next few days. This soup is very healthy and filling at only had 156 calories per serving. You can adjust the amount of spice according to your taste. I used 1/2 can of chipotle peppers in adobo sauce and it comes out pretty spicy. If you do not like spicy food, I would suggest only adding 1/2 to 1 of the chipotle peppers, you can always add more later on.
The original recipe calls for 7 cups of store bought chicken or vegetable broth. I sometimes find it easier and cheaper to make the stock myself, especially if you have some vegetables you need to use up in the refrigerator. See a recipe for vegetable stock below.
I made this soup kid friendly by adding the spice later on. In step 2, I left out the chipotle peppers and continued to boil the potatoes until tender. I scooped out a serving for Layla and pureed it in the food processor and set it aside. I then added in the peppers and continued with the recipe. To make it even easier you can find cans of the chipotle peppers in adobo sauce already pureed.
