Crispy, Cheesy Party Sandwiches

• 36 slices thin white bread, crusts removed (see note above)
• 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

1. Adjust oven rack to upper middle and lower middle positions and preheat oven to 325u0b0F. 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.
