Place a medium pot over medium heat and add the extra virgin olive oil.
Add the diced yellow onion and green bell pepper to the pot, sautéing for 4-5 minutes until the vegetables are softened and translucent.
Add the ground beef to the pot, breaking it apart with a wooden spoon, and cook until it is fully browned and no pink remains.
Stir in the chili powder, ground cumin, garlic powder, sea salt, and black pepper, coating the beef and vegetables evenly to toast the spices for 1 minute.
Pour in the diced tomatoes, tomato puree, beef bone broth, and the rinsed kidney beans.
Stir the mixture well and bring to a gentle boil.
Reduce the heat to low, cover the pot, and let the chili simmer for 20-25 minutes to allow the flavors to meld and the sauce to thicken.
Remove from heat and serve hot in a deep bowl.
