While some prefer adding a slice of tomato, we think adding Italian dressing to the bread adds a unique layer of zest and spice to a traditional grilled cheese.
Italian dressing, which is typically made up of oil, vinegar, lemon juice, oregano, crushed red pepper, garlic powder, salt, and pepper, brings a ton of depth to the bread.
Once you've assembled everything, add a layer of mayonnaise to each side of the bread. Then, using a pastry brush, spread a bit of Italian dressing over the mayonnaise.
A tablespoon of dressing is all you need. Cook the sandwich just like you would any other grilled cheese, but prepare for an even bigger blast of flavor.
