This delicious burger was inspired by Mexican Tinga, a shredded meat dish that is often made with pork, chicken or beef cooked with chorizo and served with avocodos and tomatoes. This spicy mouthful of a burger is cooled off with a tangy slaw accented with lime juice and Cotija cheese.
In a large bowl combine the beef, sausage, bay leaf, garlic, onion, chipotle peppers, tomato paste oregano, thyme, cilantro, salt and pepper. Form the meat into six equal sized patties, about 3/4 inch thick.
In another large bowl combine the cabbage, onion, lime juice, jalapeno peppers, Cotija, sour cream and cilantro; stir to combine well. Cover with plastic wrap and keep cool while grilling the patties.
Lightly brush a grill rack with oil. Arrange the patties on the grill and cook 3-4 minutes per side for medium rare. During the last 2 minutes of grilling, arrange the rolls split side down on the grill to lightly toast.
To assemble the burgers, divide the slaw between the bottom rolls. Arrange patties on top of the slaw and top each with a tomato slice followed by avocado slices, evenly dividing. Top with the remaining roll halves and serve immediately.
