- 1/2 small yellow onion
- 1/2 cup mayonnaise
- 3 tbsps freshly grated Parmigiano Reggiano
- 2 tbsps chopped fresh parsley
- Salt and pepper to taste
- 8 slices white bread, crusts removed
Preheat oven to 350 degrees.
Peel and finely chop the onion and mix with mayonnaise, cheese and parsley in a medium bowl.
Season with salt and pepper.
Using a 1-inch round cookie cutter, cut bread into 36 rounds. Spread about 1 teaspoon onion mixture onto each round, then sprinkle with more cheese and place on a cookie sheet. Heat under broiler or in the toaster oven for 2-3 minutes until bubbly and brown on top. Serve immediately.
