Cook sandwiches one or two at a time - don't overcrowd the skillet.
Set finished sandwiches on a wire rack to prevent soggy bottoms.
Add other toppings like cooked sausage, sautéed vegetables, bacon, or mushrooms if desired.
Any melty cheese works - try provolone or a cheese blend.
Sourdough, Italian bread, or Texas toast can replace white bread.
Marinara sauce, ranch, or tomato soup work for dipping instead of pizza sauce.
Refrigerate leftovers up to 3 days or freeze up to 3 months.
Reheat in a skillet over low heat, flipping frequently. Air fryer works but watch closely. Don't microwave as sandwiches will get soggy.
