Hot Sandwiches with “Rossiysky” Semi-Hard Cheese and Caramelized Onions
Instructions:
1.Caramelize the onions: Slice the onion thinly and sauté in butter with sugar and balsamic vinegar until golden and soft. Season with a pinch of salt and pepper. 2.Assemble the sandwich: Layer cheese, caramelized onion, a bit of mustard (if using), and more cheese between slices of bread. 3.Grill the sandwich: Toast in a skillet or sandwich press over medium heat until golden brown and crispy on both sides, and the cheese is melted. Serve hot — best enjoyed straight from the pan!
