My juicy steak sandwich recipe topped with crunchy baked caramelized onions and a drizzle of fresh green pesto... Best lunch sandwich!
Season the steak on all sides with some pepper and salt. Pour a little olive oil in a medium non-stick pan and place it over high heat. Once the oil is smoking hot, add the steak. Quickly sear the steak on both sides for a minute until browned.
Place it over medium-high heat and stir well. Season with a pinch of pepper and salt. Let the onion bake for about 8 to 10 minutes or until brown but still a little crunchy. Stir regularly. Once the onion is cooked, take the pan off the heat and let it cool a little. In the meantime rinse the watercress.
Combine the basil pesto and 2 tablespoons of olive oil in a small cup.
Slice the steak up. Slice the bread rolls in half and grill them lightly. Then spread a little pesto dressing on the bread, top with baked onion, watercress, sliced steak, more baked onion and drizzle with extra basil pesto. Season with a good dash of pepper. Serve.
