Recipe Card

For the Tomato Onion Jam:

ingredients

  • 4 tablespoons butter
  • 1 large sweet onion, thinly sliced
  • 5 tomatoes, seeded and finely diced
  • 3 tablespoons sugar
  • 2 tablespoons rice wine vinegar
  • 1 teaspoon salt, plus more to taste
  • black pepper, to taste

To Assemble:

ingredients

  • 2 5-10 ounces total Pre New York Strip Steaks, based on preferences
  • 2 slices thick-cut shokupan (Japanese Milk Bread), lightly toasted
  • grainy mustard, as needed

Method

  • Step 1

    To make the tomato onion jam, melt 1-2 tbsp butter in a heavy-bottomed pan. Add onions and cook on medium-high, stirring often. Once the onions start to break down (around 20 minutes), add 2-3 tablespoons of water and continue stirring. Repeat the same process until onions are completely broken down, about 40 minutes.

  • Step 2

    Add tomatoes, sugar, rice wine vinegar and 1 teaspoon salt. Bring to a boil,then reduce heat and simmer for 30 minutes to 1 hour, stirring occasionally.

  • Step 3

    Once onions and tomatoes have come together into a jammy texture, remove from heat and set aside.

  • Step 4

    Season PRE New York Strip Steaks with salt and pepper. Prepare a gas grill and preheat to medium high. Grill steaks for 3-4 minutes on one side and 2-3 minutes on the other side for medium-rare (140˚F). Let rest and slice.

  • Step 5

    Spread butter on both sides of shokupan, then top with grainy mustard and an even layer of tomato onion jam. Add 3-4 layers of steak on top of one slice of bread and top with a second piece of bread. Cut off crusts and cut into thirds.
