PREPARATION:
- To prevent sticking, spray grill with nonstick cooking spray. Prepare coals for grilling. Meanwhile, prepare Guacamole.
- Combine beef, tortilla chips, salsa, cilantro, onion and cumin in medium bowl until well blended. Shape mixture into 4 burgers. Place burgers on grid over medium heat. Grill, covered, 8 to 10 minutes (or, uncovered, 13 to 15 minutes) to medium (160°F), turning once. Place 1 slice cheese on each burger during last 1 to 2 minutes of grilling. If desired, place rolls, cut side down, on grill to toast lightly during last 1 to 2 minutes of grilling. Place burgers between rolls; top burgers with Guacamole. Serve with lettuce and tomatoes. Garnish as desired.
