Ingredients
  

2 large onions, thinly sliced

2 tablespoons olive oil

1 teaspoon balsamic vinegar

Salt to taste

1 pre-made flatbread (store-bought or homemade)

1 cup Gruyere cheese, grated

Fresh thyme leaves (optional)

Black pepper to taste

Instructions
 

In a large skillet over medium heat, add the olive oil. Once hot, add the sliced onions and a pinch of salt.

    Cook the onions, stirring occasionally, for about 25-30 minutes, until they are golden brown and caramelized. If they begin to stick, reduce the heat slightly.

      Add the balsamic vinegar to the onions and stir to incorporate, allowing the flavors to meld for another 2-3 minutes. Remove from heat and set aside.

        Preheat the oven to 400°F (200°C). Place the flatbread on a baking sheet lined with parchment paper.

          Evenly spread the caramelized onions over the flatbread, leaving a small border around the edges.

            Sprinkle the grated Gruyere cheese generously over the onions.

              Top with fresh thyme leaves (if using) and a crack of black pepper.

                Bake in the preheated oven for 10-12 minutes, or until the cheese is melted and bubbly, and the edges of the flatbread are crispy.

                  Remove from the oven and let it cool slightly before slicing.
