DirectionsTotal time: 45 minutes
Preheat a grill to medium-high heat. Meanwhile, cook bacon in a large skillet over medium heat, flipping once, until just crisp, 6 to 8 minutes; transfer to a paper-towel-lined plate. In a small bowl, stir together mayonnaise, oil, lemon juice, vinegar, chilies, garlic, and 1/4 tsp. salt; set aside.
Season patties all over with remaining 1 tsp. salt and black pepper. Arrange burgers on grill and cook, flipping once, until they reach desired doneness, about 10 minutes. During the last few minutes of cooking, top burgers with cheese and toast buns on the grill until golden brown, 1 to 2 minutes.
Arrange lettuce on buns and top with burgers and some of the mayonnaise mixture. Arrange bacon, avocado, tomatoes, onions, and pickles (if using) on burgers and serve.
