Making Juicy Grilled Flank Steak Rolls is easier than you might think! Follow these steps to create your flavorful dish:

1. Prepare the Marinade: In a bowl, combine soy sauce, olive oil, balsamic vinegar, honey, minced garlic, black pepper, and salt. Whisk until well blended.

2. Marinate the Steak: Place the flank steak in a resealable bag. Pour the marinade over the steak, ensuring it is evenly coated. Seal the bag and refrigerate for at least 20 minutes or up to 2 hours for deeper flavor.

3. Prepare the Vegetables: Slice the bell peppers, onions, and zucchini into thin strips. Set aside.

4. Preheat the Grill: Preheat your grill to medium-high heat.

5. Remove Steak from Marinade: Take the flank steak out of the marinade, allowing excess marinade to drip off. Discard the leftover marinade.

6. Assemble the Rolls: Lay the flank steak flat on a clean surface. Distribute the sliced vegetables evenly over the surface of the steak. Beginning from one end, carefully roll the steak around the vegetables to form a tight roll.

7. Secure the Rolls: Use kitchen twine or toothpicks to secure the ends of the roll to ensure it maintains its shape while grilling.

8. Grill the Rolls: Place the steak rolls on the preheated grill. Grill for about 5-7 minutes on each side, or until the steak is medium rare, with an internal temperature of about 135°F (57°C).

9. Remove and Rest: Once cooked to your liking, remove the steak rolls from the grill and allow them to rest for about 10 minutes. This helps retain the juices.

10. Slice and Serve: Carefully remove the twine or toothpicks and slice the rolls into 1-inch pieces.
