here is a great party sandwich recipe that can be increased to make up to 24 sliders for entertaining. this is another baked sandwich recipe that can be prepared ahead and then baked just before serving to guests. any type of sandwich meats and cheeses can be used, based on the time of year or the theme of the party. i made these for my Oscar night party and used turkey pastrami and provolone cheese with red onions. any type of condiments or toppings can be used. the secret to these sandwiches is to use small-sized dinner rolls with the poppy-seed topping sauce. the sauce is what your guests will comment about, as it takes the sandwiches from ordinary to extraordinary.
to make the sauce: in a small bowl, mix together these ingredients — 1 tablespoon poppy seeds, 1 1/2 tablespoons yellow mustard, 1/2 cup melted margarine or butter, 1 tablespoon minced onion, and 1/2 teaspoon Worcestershire sauce.
Pour the sauce over the sandwiches just before baking. Use as much sauce as needed to cover the tops of the sandwiches without drenching. Allow the sandwiches to rest about 5 minutes before baking. cover the sandwiches with foil, bake at 350 degrees for 12-15 minutes or until the cheese is melted. uncover and cook for 2 more minutes until the tops are slightly browned. serve warm.
this is perfect for parties, since the sandwiches can be assembled and kept in the refrigerator until ready to top with sauce and bake.
