I used this recipe as a guideline, and came out with some pretty delicious soup. If the prospect of grating up a bunch of fancy cheese and melting it into a pot of pureed veggies sounds like something you'd enjoy, this is definitely a soup for you.
Dietary note: This is largely vegetarian, depending on your tolerance for cheese that may use animal rennet. If you only eat rennet-free cheese and rennet-free smoked gouda is something you can get your hands on, not a problem. If not, I'm afraid the cheese is what makes this soup (although you might be able to get something similar in taste with a combination of liquid smoke and some kind of sharp white vegetarian cheese).
Accessibility note: This is a pretty easy soup chopping-wise; it's pureed, so no need to be finicky about chopping the veggies. It does require an immersion blender (or at least some kind of blender) and opening some jars, though.
