In a large pot on medium-high heat, cook the ground beef until browned.
Turn the heat down to medium and add the onions and garlic. Cook until softened, about 6 minutes.
Add the tomato paste and cook for 2 minutes. This can burn easily, so make sure to continue stirring.
Add in the chili powder, oregano, onion powder, garlic powder, fire-roasted tomatoes, and chicken stock. Bring to a boil.
Add in the rinsed beans and pumpkin.
Cover and simmer for at least 30 minutes.
Serve, and enjoy!
