This soul-warming chili is simple to prepare. Using leftover beef Brisket, add onion, jalapeno peppers, garlic, chilies and tomatoes, then simmer to deepen the chili's rich flavors.
Heat oil in stockpot over medium heat until hot. Add onion, jalapeño pepper and garlic; cook 5 to 7 minutes or until onion is tender, stirring occasionally.
Stir in beef Brisket, chiles and tomatoes; bring to a boil. Reduce heat; cover and simmer 20 minutes to develop flavors, stirring occasionally. Remove from heat. Stir in 2 tablespoons sour cream.
Garnish with additional sour cream, tortilla chips, cheese, avocado or guacamole, if desired.
