The Spanish word for midnight is medianoche, and this type of sandwich is often enjoyed as a late-evening snack. Traditionally, the recipe calls for Cuban bread; we've substituted Hawaiian sweet bread, which is widely available in supermarkets. Pressing the sandwich with a skillet as it cooks not only melts the cheese but also toasts the bread by compressing the delicious layers.
2 tablespoons Dijon mustard
1 tablespoon light mayonnaise
1/4 teaspoon freshly ground black pepper
8 (1 1/2-ounce) slices Hawaiian sweet bread
6 ounces reduced-fat Swiss cheese, thinly sliced
4 sandwich-cut dill pickles, cut in half crosswise
2 plum tomatoes, thinly sliced
How to Make It
Combine first 3 ingredients in a small bowl. Spread about 1 1/2 teaspoons mustard mixture evenly over each bread slice. Divide cheese, pickles, and tomatoes evenly over each of 4 bread slices; top with remaining bread slices.
Heat a nonstick grill pan over medium-high heat. Coat pan with cooking spray. Add 1 sandwich to pan. Place a cast-iron or heavy skillet on top of sandwich; gently press to flatten. Cook 45 seconds on each side or until cheese melts and bread is toasted (leave cast-iron skillet on sandwich while it cooks). Repeat procedure with remaining sandwiches. Cut sandwiches in half diagonally.
