Heat a large pot over medium high heat and add in your olive oil and then your meat.
Season your meat with 1 tsp salt, and 1/2 tsp black pepper.
While your meat is browning, chop your onion, green pepper, and garlic.
Once your meat is cooked through, drain it if necessary and remove it from the pan. I just set it aside in a bowl.
In your same heated pot, add in your chopped onions and green peppers and cook for about 5 minutes or until translucent.
Add in your garlic and cook for 2 more minutes then remove from heat.
Once your garlic is cooked, add in 1/2 tsp salt, 1/2 black pepper, cumin, chili powder, and cayenne pepper and stir together.
Add your meat back to the pan and add in the rest of your ingredients: Tomato sauce cans, diced tomatoes, beans, cocoa powder, and oregano.
Stir everything together to combine, reduce your heat to low, cover the pot and simmer for 2 hours while stirring occasionally OR place in the crockpot on low for 7-8 hours.
