In a large pot, cook the chopped bacon over medium heat until crispy. Once done, remove the bacon and set it aside, leaving the rendered fat in the pot.

In the same pot with the bacon fat, add the diced onion. Sauté until translucent, and then add the minced garlic—cooking for another minute or until fragrant.

Pour in the broth, followed by the drained and rinsed white beans and the thyme. Stir to combine.

Bring the mixture to a simmer and let it cook for about 10 minutes to allow the flavors to blend beautifully.

Stir in the reserved bacon and, if using, add the kale or spinach. Heat everything through until the greens are wilted.

Season with salt and pepper according to your preference. Serve hot and enjoy!
