Not your ordinary leftover-turkey sandwich, this grilled creation, with cheese and marinara sauce, is filled with irresistible flavor.
Heat a medium nonstick skillet or a griddle over medium heat. Working on a clean surface, place a slice of cheese on top of each of 4 bread slices. Spread 1 to 2 tablespoons of marinara sauce over the cheese; sprinkle evenly with Parmesan. Layer each with turkey and a final slice of cheese. Top each sandwich with another bread slice, and lightly butter outsides.
Working in batches, grill sandwiches until bread is golden brown on the bottom, about 3 minutes. Using a spatula, turn sandwiches, and grill until other side is golden brown and cheese is melted, about 3 minutes more. Slice in half, and serve warm.
Use fresh turkey sliced at the deli counter instead of prepackaged cold cuts, which contain more sodium and preservatives.
