In a 4 quart pot or larger, heat 4 tablespoons of the oil on medium high heat.
Add ground beef. Sear until mostly cooked for 5-7 minutes, breaking the larger pieces of ground meat apart with a wooden spoon. Once cooked, remove beef from the pot and set aside.
Turn the stove down to medium heat. Add the remaining oil into the pot. Add the onions and green pepper. Cook for 3 minutes, stirring occasionally. Add the garlic, and cook for 1 minute while stirring.
Add the tomato paste in with the vegetables. Cook for one minute while stirring.
Add the remaining ingredients, stirring to incorporate.
Bring the chili to a rapid simmer. Then turn the heat down to its lowest setting. Cover and cook on a low simmer for 45 minutes, stirring occasionally.
