INGREDIENTS

8 oz Ground beef 93% lean

0.5 medium Yellow onion

1 tsp Extra virgin olive oil

0.5 tsp Sea salt

0.25 tsp Black pepper

2 large Butter lettuce

1 slice Tomato

1 tsp Yellow mustard

PREPARATION

• 1

  Thinly slice the yellow onion into half-moons.

• 2

  Heat the olive oil in a small skillet over medium-low heat. Add the onions and cook, stirring occasionally, until they are soft and deep golden brown, about 15 to 20 minutes.

• 3

  While the onions caramelize, form the ground beef into one large, uniform patty. Season both sides evenly with sea salt and black pepper.

• 4

  Heat a cast-iron skillet or grill pan over medium-high heat. Place the patty in the hot pan and sear for 4-5 minutes per side, or until it reaches your preferred level of doneness.

• 5

  Wash and pat dry the butter lettuce leaves to use as your 'bun'.

• 6

  Place the cooked beef patty onto the lettuce leaves. Top with the warm caramelized onions, the tomato slice, and a dollop of yellow mustard.

• 7

  Wrap the lettuce tightly around the burger and serve immediately.
