In a large Dutch oven, add the olive oil, chopped onion and minced garlic.
Saute for a few minutes until the onions are translucent.
Add the lean ground beef and continue sauteing until the beef is thoroughly cooked.
Add in all the remaining ingredients and stir until well combined.
Increase the temperature and bring the chili to a boil, while stirring.
Allow the chili to boil for a few minutes, continually stirring.
Reduce the heat to a simmer.
Simmer for about 30 minutes, stirring frequently to prevent sticking to the bottom of the pan.
Turn off the heat and cover the pot with the lid, allowing it to cool for 10-15 minutes to serving temperature.
Serve plain, or topped with sour cream, jalapenos, or parmesan cheese.
