INGREDIENTS

7 oz 93% lean ground beef

0.5 tsp olive oil

0.5 medium yellow onion

1 slice sourdough bread

1 tbsp Dijon mustard

0.5 cup arugula

0.25 tsp sea salt

0.25 tsp black pepper

1 tsp balsamic vinegar

PREPARATION

• 1

  Thinly slice the yellow onion into uniform half-moons.

• 2

  Heat the olive oil in a non-stick skillet over medium-low heat and add the onions with a pinch of the sea salt.

• 3

  Sauté the onions slowly for 15-20 minutes, stirring occasionally, until they reach a deep golden brown color.

• 4

  Stir in the balsamic vinegar to deglaze the pan, then remove the onions and set them aside.

• 5

  Wipe the skillet clean and return it to the stove over medium-high heat.

• 6

  Form the ground beef into a single large, flat patty and season both sides with the remaining sea salt and black pepper.

• 7

  Sear the beef patty for 3-4 minutes per side until a dark crust forms and it is cooked to your desired level of doneness.

• 8

  While the beef cooks, toast the sourdough bread slices until they are golden and firm.

• 9

  Spread the Dijon mustard evenly across one slice of toasted bread.

• 10

  Assemble the sandwich by layering the fresh arugula, the beef patty, and the caramelized onions between the sourdough slices.
