I had a bowl of homemade chicken stock begging to be turned into some sort of soup, but didn't have anything much in the veggie drawer in the fridge.
Then I had a lightbulb moment.
Apple's Persian Onion Soup from the Leon 2 book.
It's not a quick recipe - you need to sweat off the onions for 15 mins first, add some spices and cook them through....
before adding stock and simmering it until it all softens down to a delish bowl of soup.
Probably about 45 mins in all but well worth it!
If you fancy making it, you can find the recipe here
