Ingredients
  

For the marinade
  • 1.5 to 2 pounds flank steak, trimmed
  • 1/3 cup balsamic vinegar
  • 1/4 cup extra-virgin olive oil
  • 2 tablespoons honey or maple syrup Optional sweetener
  • 3 cloves garlic, minced
  • 1 teaspoon Dijon mustard
  • 1 teaspoon dried oregano or 1 tablespoon fresh, chopped
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1/2 teaspoon freshly ground black pepper
For the topping
  • 8 ounces fresh mozzarella, sliced
  • 2 cups grape or cherry tomatoes, halved (or 2 large tomatoes, sliced)
  • 1 cup fresh basil leaves
  • Balsamic glaze (store-bought or homemade) for drizzling
  • Optional: flaky sea salt for finishing

Method
 

Preparation
  1. Make the marinade. In a medium bowl, whisk together balsamic vinegar, olive oil, honey, minced garlic, Dijon, oregano, salt, and pepper.
  2. Marinate the flank steak. Place steak in a resealable bag or shallow dish and pour the marinade over it. Massage into meat and let sit at least 30 minutes at room temperature, or up to 4 hours in the fridge.
  3. Prep your grill. Preheat to medium-high (about 400–450°F). Lightly oil grill grates or pan to prevent sticking.
Cooking
  1. Grill the steak. Remove from marinade, letting excess drip off. Grill 4–6 minutes per side for medium-rare.
  2. Rest, then slice. Transfer steak to a cutting board, tent with foil, and rest for 10 minutes. Slice thinly against the grain.
Assembly
  1. On a serving platter, layer slices of steak with fresh mozzarella, tomato halves or slices, and basil leaves. Drizzle with olive oil and balsamic glaze. Finish with flaky sea salt if desired.
  2. Serve warm or slightly cooled with extra balsamic glaze and fresh basil.

Notes

For a lighter recipe, use less oil or substitute honey with a sugar-free sweetener. Add red pepper flakes for a bit of heat. To make indoors, use a cast-iron skillet on high heat for a great sear.
