Ingredients
  

1 pound flank steak, thinly sliced

2 large onions, caramelized

1 cup Gruyère cheese, shredded

3 cloves garlic, minced

2 tablespoons balsamic vinegar

1 tablespoon fresh thyme leaves

Salt and pepper to taste

3 tablespoons olive oil

Toothpicks or kitchen twine

Instructions
 

Prepare the Steak: If not already thinly sliced, place the flank steak between two sheets of plastic wrap and gently pound it to about 1/4-inch thickness.

    Caramelize the Onions: In a skillet, heat 2 tablespoons of olive oil over medium heat. Add the sliced onions and cook slowly, stirring occasionally, for about 20-25 minutes until golden brown. Add minced garlic and thyme, cooking for an additional 2 minutes. Stir in balsamic vinegar, then remove from heat.

      Assemble Pinwheels: Lay the thinly sliced steak flat on a clean surface. Spread an even layer of the caramelized onions on top, followed by a generous sprinkle of shredded Gruyère cheese.

        Roll and Secure: Starting at one end, tightly roll the steak into a pinwheel. Secure the roll with toothpicks or wrap with kitchen twine to keep it intact.

          Cook the Pinwheels: In the same skillet used for the onions, add the remaining tablespoon of olive oil and heat over medium-high. Sear the pinwheels for about 3-4 minutes on each side until nicely browned and cooked to your desired doneness.

            Rest and Slice: Remove pinwheels from the skillet and allow them to rest for 5 minutes before slicing into spirals for serving.

              Final Seasoning: Season each slice with extra salt and pepper to taste.

                  - Presentation Tips: Arrange the pinwheels on a serving platter and drizzle with a reduction of the pan juices. Garnish with additional fresh thyme for a vibrant look. Serve with a side of mixed greens for color contrast.
