I make a pretty simple potato and kale soup that's a favorite in my house. It's not a recipe per se with set quantities, I just wing it.
I start in a large pot with diced carrot, onion, and celery sautéed for a few minutes, then add spice at the end to bloom: rosemary, thyme, black pepper at a minimum. Sometimes I add some garlic powder and/or paprika for a touch of daring. Next add beans, usually 1 or 2 cans of cannellini beans. Then add chicken broth, homemade if possible. About 2 quarts of broth (or 2 liters if you use a sensible measurement system). Sometimes add another 2 of water to expand the amount. Salt to taste, cover, and bring to a simmer.
After at least 30 minutes add 3-4 potatoes diced into bite-sized pieces. Simmer for another 10 minutes or until the potatoes are tender. At this point, I usually scoop out a few ladles-full and blend it smooth, then add back in to thicken the soup. Add some chopped fresh kale to wilt in the broth for a few minutes, then serve.
It's warm and hearty, can be vegan if desired by using vegetable broth, and can be ready in about an hour.
end note: If you want to use the whole kale leaf including the rib, dice the rib and add it to the carrot/onion/celery sautee. Keep in mind if you do this and also do the blending step, your broth will be greenish. Still tastes good though and you get more fiber.
