Ingredients
  

For the Balsamic Grilled Flank Steak:

  • 1 ½ pounds flank steak
  • ⅓ cup balsamic vinegar
  • ¼ cup olive oil
  • 3 cloves garlic minced
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper

For the Caprese Salad:

  • 2 large ripe tomatoes sliced
  • 8 ounces fresh mozzarella sliced
  • 20 fresh basil leaves
  • 1 tablespoon balsamic glaze
  • Sea salt and freshly ground black pepper to taste

Instructions
 

  • Marinate the Flank Steak: In a bowl, whisk together balsamic vinegar, olive oil, minced garlic, Dijon mustard, oregano, salt, and pepper. Place the flank steak in a resealable bag or shallow dish, pour the marinade over the steak, and refrigerate for at least 30 minutes (up to 4 hours).
  • Prepare the Caprese Salad: Slice tomatoes and mozzarella. Arrange them on a plate, alternating with basil leaves. Drizzle lightly with olive oil (optional) and season with salt and pepper.
  • Grill the Flank Steak: Preheat your grill to medium-high heat. Remove steak from the marinade, discarding the marinade. Grill the steak for 4-6 minutes per side for medium-rare, or until desired doneness.
  • Rest and Slice the Steak: Let the steak rest for 5-10 minutes before slicing thinly against the grain.
  • Assemble the Dish: Place the sliced steak over the prepared Caprese salad. Drizzle with balsamic glaze and garnish with extra basil if desired. Serve immediately.

Notes

  • For best results, marinate the steak for at least an hour to allow the flavors to penetrate.
  • Feel free to add grilled vegetables like zucchini or bell peppers to the Caprese for extra flavor and texture.
  • You can also use burrata cheese instead of mozzarella for an ultra-creamy twist.
  • Leftovers can be stored in the fridge for up to 2 days. Reheat steak gently to avoid overcooking.
