Start by laying the flank steak flat on a clean cutting board. Pound the meat to about 1/4 inch thick and season with salt and black pepper.

In a medium bowl, combine softened cream cheese, garlic powder, and shredded cheese. Fold in fresh spinach until evenly mixed.

Spread the cheese and spinach mixture evenly across the flank steak, leaving a half-inch border. Roll the steak tightly from the long side and secure it.

Slice the steak log into 1-inch thick pinwheels and preheat your oven to 375°F.

Arrange the sliced pinwheels on a baking sheet lined with parchment paper and bake for 15-18 minutes.

Once baked, let the pinwheels rest for 5 minutes, then garnish with herbs and drizzle with balsamic glaze before serving.
