INGREDIENTS

6 oz Ground beef (93% lean)

0.5 whole Whole wheat burger bun

0.5 medium Yellow onion

0 tsp Extra virgin olive oil

0.25 tsp Sea salt

0.25 tsp Black pepper

1 tsp Dijon mustard

1 leaf Romaine lettuce

1 slice Tomato

PREPARATION

• 1

  Slice the yellow onion into thin half-moons.

• 2

  Heat the extra virgin olive oil in a small skillet over medium-low heat, add the onions, and cook slowly until soft and golden brown, about 15 minutes.

• 3

  While the onions are caramelizing, shape the ground beef into a thick, uniform patty and season both sides evenly with sea salt and black pepper.

• 4

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

• 5

  During the last minute of cooking, place the split whole wheat bun face-down in the skillet to lightly toast until crisp.

• 6

  Spread the Dijon mustard on the bottom bun, then layer with the romaine lettuce, tomato slice, beef patty, and a generous heap of caramelized onions before closing with the top bun.
