Place a large pot over medium-high heat and add 1 tablespoon olive oil. Once simmering, add beef and cook breaking it with a wooden spoon until it has browned and almost cooked through. Drain grease, leaving only about 1 tablespoon.

Add onion and garlic, cook for another 3 minutes, until the onions have softened.

Add chili powder, Worcestershire sauce, cocoa powder, green chiles, tomato paste, tomato sauce, crushed tomatoes, and beans. Stir and bring to a simmer.

Add 1-2 cups of water, depending on how thin you want the chili, simmer partially covered for 15 minutes.

Taste and adjust for salt, pepper, and more chili powder.

Serve hot with preferred toppings.
