Heat olive oil in a large pot over medium heat.

Add ground round beef and sauté until browned.

Drain and set aside.

In the same pot, sauté diced green pepper, diced celery, onion, and minced garlic until tender.

Add the browned beef back to the pot along with chopped black olives, kidney beans, stewed tomatoes, brown sugar, chili powder, cumin, minced chili pepper, and oregano vinegar.

Let the mixture simmer for approximately 15 minutes.

Then, add 1 cup of water and continue to simmer for another 15 minutes.

Adjust the amount of water according to your preferred consistency.

Serve hot and enjoy!
