These tiny triple-decker sandwiches are buttery, toasty, and oozing with cheese. They're a cross between a crouton and a grilled cheese. You'll need two loaves of bread for this recipe—I used Pepperidge Farm Original White.

Make these a day or two in advance and keep them well wrapped in the fridge until you need them. As soon as the first guest arrives, arrange a few on a baking sheet and cook them in a preheated oven. Hostess with the mostest, and not a bead of sweat.

Ingredients

  • 36 slices thin white bread, crusts removed (see note)
  • 8 ounces (2 sticks) unsalted butter, melted
  • 1 (14-ounce) can hearts of palm, drained and finely chopped
  • 4 ounces sharp cheddar cheese, finely grated
  • 3 tablespoons mayonnaise
  • 2 tablespoons finely minced onion
  • 1 teaspoon dried mustard
  • 1 teaspoon grated lemon zest
  • 1/8 teaspoon cayenne pepper
  • Salt and pepper

Directions

  1. Adjust oven rack to upper middle and lower middle positions and preheat oven to 325°F. Brush both sides of each slice of bread with butter; set aside.

  2. In medium bowl combine hearts of palm, cheddar, mayonnaise, onion, mustard, zest, and cayenne. Season to taste with salt and pepper.

  3. Spread about 1 tablespoon cheese mixture on 24 slices of bread. Arrange 1 slice of cheese mixture-coated bread on a second slice of cheese mixture-coated bread, then top that slice with one of the remaining buttered slices. Gently press the triple-decker sandwiches down to adhere, and cut each into 3 pieces.

  4. Arrange sandwiches on two baking sheets, leaving about 1 inch between them. Bake until golden, about 20 minutes, carefully flipping the sandwiches with a spatula halfway through baking. Transfer trays to cooling racks and cool about 5 minutes before serving.
