Lay the butterflied flank steak flat on a clean work surface and cover with plastic wrap. Using a meat mallet or rolling pin, pound to an even 1/2-inch thickness as needed.
02 -
Drizzle olive oil over the surface of the steak. Sprinkle evenly with garlic powder, Italian seasoning, salt, and black pepper.
03 -
Scatter shredded cheese evenly over the steak, leaving a small border along the edges. Distribute chopped spinach and roasted red peppers evenly across the cheese if using.

Starting from one short end, roll the steak tightly into a log. Use butcher’s twine to tie the log securely at 1 to 2-inch intervals.

Preheat a skillet or grill over medium-high heat. Sear the steak log for 2 to 3 minutes on all sides until evenly browned.

Transfer the seared steak log to a 375°F oven. Roast for 15 to 20 minutes, until the internal temperature reads 135°F for medium rare or 145°F for medium doneness.

Allow the meat to rest for 5 to 10 minutes. Remove butcher’s twine and slice into 1-inch thick pinwheels. Serve warm.
