If you are making Grilled Cheese for a crowd, you can use a large skillet or electric griddle. You can also make them in the oven. Preheat the oven to 350 and put two baking sheets in the oven while it preheats. Make up your sandwiches, and when the pans are hot, place the sandwiches on one pan, and then place the other pan on top. Bake until the bread has a golden brown crust and the cheese is melted.
