Heat a large skillet over medium-high heat and add the extra virgin olive oil.
Add the ground beef to the skillet, breaking it apart with a wooden spoon, and sear until beautifully browned and cooked through.
Transfer the browned beef into your slow cooker, ensuring you scrape in all those flavorful browned bits from the pan.
Add the kidney beans, diced tomatoes, yellow onion, and green bell pepper to the slow cooker basin.
Sprinkle in the chili powder, ground cumin, sea salt, and black pepper, then pour in the beef broth to provide moisture.
Stir everything together until the spices are evenly distributed throughout the mixture.
Set the slow cooker to low for 6 to 8 hours, allowing the flavors to develop into a deep, savory profile.
Ladle the hot chili into bowls and serve immediately, enjoying the hearty texture of this clean-eating staple.
