Steps
1
Thinly slice the onion. Brush a large grill pan with the oil and heat on medium-high. Add onions and grill 7–8 min., until tender.

Meanwhile, finely chop 1 jalapeño and drain the green chiles. In a medium bowl, add ground beef, chopped jalapeños, green chiles, salt, and pepper. Mix to combine. Divide beef into 4 equal portions and shape into patties. When onions are done, transfer to a plate. Add burgers to pan and grill 3–4 min. per side, until desired doneness.

Meanwhile, chop the cilantro. Thinly slice remaining jalapeño. Into a small bowl, zest half of lime and squeeze all the juice. Stir in mayonnaise and chopped cilantro.

Toast the buns, if desired. Spread cut sides of buns with cilantro mayonnaise. Top with 2 lettuce leaves, burger, grilled onion, and sliced jalapeño.
