Chorizo Burgers with Green Chile Aioli

Directions

1. In a large bowl, combine beef and chorizo, mixing lightly but thoroughly. Shape into six 6-in. patties. Grill burgers, covered, over medium heat or broil 3-4 in. from heat until a thermometer reads 160°, 6-8 minutes on each side. Top with cheese; grill, covered, until cheese is melted, 1-2 minutes longer.
2. Meanwhile, combine mayonnaise, chiles, cilantro and lime juice. Top burgers with sauce, tomato, avocado and, if desired, optional toppings. Wrap in lettuce leaves.
