Grab a 5-quart pot and heat over medium heat. Remove the skin from the onion and dice into ¼-½” pieces. Then, remove the seeds from the jalapeno and dice.
Spray pot with cooking spray and sauté onion, jalapeno, frozen garlic cubes (or minced garlic), oregano, and cumin for about 5 minutes.
Serve your chili hot! Top with chip crumbles, sour cream/Greek yogurt, fresh avocado, jalapeno, shredded cheese, or homemade croutons. Enjoy!
