Peanuts make some of the best soup around. There's lots of variations, but I'll share a favourite inspired by Sopa
de Mani, a Bolivian dish.
1 cup roasted peanuts (since yours are pre-salted i'd probably give them a rinse)
a few garlic cloves
1 leek (or red onion)
1 red pepper
1 carrot, finely chopped or shredded
1 potato, diced
3 cups of stock (any kind will do)
3 tbsp of preferred cooking fat
Sauté the leek, red pepper and carrot until they start to break down a bit. add the potatoes and peanuts, just stir them in gently to coat in the oil then pour the stock over top, add a bay leaf and simmer for about 40 min. When done, blend the soup with a hand mixer or blender.
I like to season it with black pepper, thyme, chilis and coriander but the soup base is really flexible to whatever seasonings you like. Top with some extra salted peanuts.
A lot of recipes call for celery, I'm not a fan so I leave it out.
If you are a low carb kinda person, swap the potato for a chayote or summer squash.
