White Bean & Kale Soup

1/2 white onion diced small
1.5 Cup diced/chopped carrot
3 - 4 celery stalks chopped
4 cups mushroom broth
5 cans great northern white beans
4 big leaves of Lacinato Kale
fresh oregano if you can get it
1/2 lemon, juiced

Put the first 3 ingredients in a big pot and JUST cover with broth. set to simmer. Meanwhile, open, drain and rinse 3 of the cans of beans. Put the cleaned beans in your blender, pour in some broth, till it comes about half way up the beans in the blender. I used my magic bullet and did this in 2 batches. Blend till smooth-ish, add to simmering veggies. Add the rest of the broth to the pot. Chop up your kale, and oregano and add them to the pot. Open, drain and rinse the other 2 cans of beans and add them whole to the soup. Squeeze your 1/2 lemon over it. Low boil simmer for around 15 min
