Method

Preparation of Ingredients

  1. 1

    Caramelize the Onions

    Slice the medium onion thinly. In a skillet, heat 1 tablespoon of olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until they are golden brown and caramelized, about 15-20 minutes.

  2. 2

    Prepare the Steak

    Slice the 10 oz tri-tip steak against the grain into thin slices. Season lightly with salt and pepper if desired.

  3. 3

    Prepare the Arugula

    Rinse the arugula under cold water and pat it dry with a paper towel.

Assembly of the Sandwich

  1. 4

    Spread Condiments

    Take 2 slices of sourdough bread and spread 1 tablespoon of Dijon mustard on one slice and 1 tablespoon of garlic mayo on the other slice.

  2. 5

    Layer Ingredients

    On the slice with Dijon mustard, layer the sliced tri-tip steak, followed by the provolone cheese, caramelized onions, and arugula. Top with the slice of bread spread with garlic mayo.

  3. 6

    Toast the Sandwich

    In a skillet or grill pan over medium heat, place the assembled sandwich. Grill each side for about 3-4 minutes or until the bread is golden brown and the cheese is melted.

  4. 7

    Serve

    Remove the sandwich from the skillet, slice in half if desired, and serve warm.
