COOK IT.
Preheat your Pit Boss Griddle on HIGH heat.
Place flank steak on a cutting board and slice horizontally across, to open, without completely cutting through. Use a meat mallet to pound to even thickness, if needed.
Season the steak on both sides evenly with Pit Boss Chophouse Steak Rub. Set aside.
In a mixing bowl, use a hand mixer to combine cream cheese, sour cream, sun dried tomatoes, and fennel.
Spread cream cheese mixture on steak, then layer spinach and provolone. Roll steak, then tie with kitchen twine every 2 inches. Slice steak in between ties to cut into individual portions.
On the griddle top, carefully add oil and heat.
Add steak rolls and sear 5 minutes per side.
Remove steaks from the grill and allow to rest for 5 minutes. Serve warm.
