Step 1

Cut beef chuck into 1/2 inch cubes.

Step 2

Pour 3 tablespoons of oil into a dutch oven or large pot. Turn the eye on high and allow the oil to heat.

Step 3

Place onion and garlic into the pot and cook for 2 minutes. Reduce the heat to medium-high, then add the beef cubes. Brown the meat, while stirring constantly.

Step 4

Once the meat has browned slightly (with no red showing), lower the temperature to medium.

Step 5

Add Italian seasonings, chili powder, smoked paprika, cumin, brown sugar, vinegar, tomatoes, beans, black pepper, salt, diced jalapenos, and red pepper flakes. Mix well.

Step 6

Simmer for about 10 minutes, then add corn tortilla flour (or masa harina) to help thicken the chili.

Step 7

Cook for another 10 minutes, or until chili thickens.

Step 8

Serve and top with sour cream, shredded cheese, tortilla chips, and avocado slices.
