Grilled Mac and Cheese Sandwich

To make the garlic butter spread:

1. In a small bowl, whisk together the butter, Italian seasoning, and garlic powder to blend.

To assemble the sandwiches:

1. Brush one slice of bread with the seasoned butter and place butter-side down on work surface.
2. Top the bread with one to two thin slices of mozzarella. Carefully cover with 1/2 cup (115 grams) leftover macaroni and cheese.
3. Cover with another one to two slices of mozzarella and top with bread.
4. Brush the top with more seasoned butter. Repeat with remaining Mac and cheese and bread to make four sandwiches in all.
5. Place a skillet over medium-low heat.
6. Gently transfer the assembled sandwich to the hot skillet. Cover and cook, adjusting the heat between medium-low and low as needed, until golden, about 2 minutes per side.
7. Carefully flip, cover again, and cook the sandwich on the other side until the bread is golden and cheese is melted. Repeat with remaining sandwiches.
8. Serve warm from the skillet.
