Kale, White Bean, and Sweet Potato Soup.
The original recipe uses chicken, but you can easily make a vegetarian recipe by replacing it with homemade vegetable stock.
While this is a great recipe, it does require some adjusting: 3 saucepans, and running the oven for almost an hour to roast one head of garlic doesn´t seem very efficient. As some commenters have suggested, it would be better to cut the garlic pre-baking. You could also roast garlic in a toaster oven for energy efficiency.
Another suggestion is to add 1 tsp smoked paprika and served w/ grated parmesan. Click here to view this recipe and happy cooking!
