Simmer over low heat, slightly uncovered, for about 1 ½ hours, stirring occasionally.
Simmer uncovered for a remaining 30 minutes to reduce the liquid in the chili to a thicker consistency.
Season with salt and pepper according to taste.
Garnish with grated cheddar and sliced avocado and serve with tortilla chips.
In Your Kitchen:
If you like beans in your chili, go ahead and add a can of rinsed beans to the existing recipe! There should be enough liquid to help balance out the addition of beans and still achieve the right thickness or consistency. Adjust the amount of chipotle peppers and chili powder to suit your desired level of spiciness.
