Parmesan Cheese Rounds

• 1 loaf thin sandwich bread
• 1 cup mayonnaise
• 1/2 cup freshly grated Parmesan
• Yellow mustard, for spreading
• 10 to 12 small white onions (pearl or boiling onions), very thinly sliced

1. Preheat the broiler to 425 degrees F.
2. With a 2 1/8-inch cookie cutter, cut 2 rounds out of each slice of bread.
3. Arrange the rounds on a baking sheet and place 5 inches from the heat source.
4. Toast the bread on one side until they are golden brown, 3 to 5 minutes.
5. Using a whisk, mix together the mayonnaise and Parmesan in a small bowl.
6. Remove the bread from the oven and turn the rounds over to the untoasted sides.
7. Spread each with a thin layer of mustard.
8. Put 1 onion slice on top and cover with about 1 teaspoon of the mayonnaise mixture, spreading the mixture across the onion and bread.
9. Broil until golden, about 1 minute.
10. Never take your eyes off these; the time varies with different ovens.
11. Work in batches of 24 rounds.
12. Serve one batch hot while the next is cooking.
