Creating Juicy Grilled Flank Steak Rolls is an effortless process when you follow these clear steps:

1. Marinate the Steak: In a bowl, combine olive oil, minced garlic, salt, black pepper, smoked paprika, and cumin. Add the flank steak, ensuring it’s coated thoroughly. Let it marinate for at least 1 hour.

2. Prepare Fillings: While the steak is marinating, chop the fresh spinach and slice the roasted red peppers. Set aside the feta cheese for later use.

3. Preheat the Grill: Heat your grill to medium-high. Ensure that the grates are clean to prevent sticking.

4. Roll the Steak: Once marinated, lay the flank steak flat on a clean surface. Spread the chopped spinach, roasted red peppers, and crumbled feta cheese evenly over the steak.

5. Secure the Roll: Starting from one end, tightly roll the flank steak, ensuring the fillings stay inside. Use toothpicks to secure the roll every couple of inches, preventing it from unraveling during grilling.

6. Grill the Rolls: Place the secured steak roll on the preheated grill. Cook for about 15-20 minutes, turning occasionally until the steak reaches your desired level of doneness (145°F for medium-rare).

7. Rest and Slice: Once cooked, remove the steak roll from the grill. Let it rest for about 5 minutes before slicing into bite-sized pieces.

8. Remove Toothpicks: Carefully pull out the toothpicks before serving to avoid any accidents.

9. Garnish (Optional): For added flavor, drizzle with some extra olive oil or a sprinkle of fresh herbs before serving if desired.
