Italian Grilled Cheese Sandwiches is my favorite twist to a traditional grilled cheese! Any dinner that's ready in 15 minutes is my kind of easy weeknight meal!
Spread butter on the "outside" pieces of bread that will touch the griddle when cooking.
Spread marinara sauce on the inside pieces of the sandwich bread.
Layer mozzarella and cheddar cheese on top of the marinara sauce. Top with fresh basil, if using.
Place bread slices together to make a sandwich. Place sandwich on hot griddle or skillet and cook until cheese is melted and bread is golden brown and toasted.
