In a large pot over medium heat, add the ground pork and cook until browned, breaking it apart, about 5-6 minutes.
Add the onions, bell pepper, and garlic to the pot. Sauté for 3-4 minutes until softened.
Stir in the chili powder, dried oregano, salt, and pepper. Cook for 1 minute to release the flavors.
Add the butternut squash, butter beans, and vegetable stock. Bring to a boil, then reduce heat and simmer for 15-20 minutes, until the squash is tender.
Stir in the kale and cook for another 3-5 minutes, until wilted.
