Minute Steak Sandwiches with Caramelised Onions and Cheese Sauce.
Preheat a heavy non-stick frying pan. Add 1 T of oil. Add sliced onions, sugar and Green Onion Seasoning. Put a lid on the pan and cook the onions slowly, with the lid on, while stirring now and again (about 10 minutes). Add the balsamic vinegar and stir-fry, without a lid, until onions are well glazed. Remove from the pan and keep warm covered with foil.
Wipe the pan clean with paper towel and reheat until hot. Add the oiled steaks to the pan. Cook on one side until browned and only then turn to cook the other side very briefly.
While cooking the steaks drizzle or brush both sides of the bread halves with oil and toast it on a griddle pan. Spread a generous coating of your preferred Sauce on the bottom half of the bread.
Pile the onions on. Slice the steaks into 1.5 cm wide strips and place it on the onions. Drizzle with any remaining Sauce. Press the top half of the toasted bread down over the filling. Cut into 4 portions.
