- In a bowl, stir together the mayonnaise, Parmesan, mushrooms, and onion rings. Spread on lightly toasted party rye or pumpernickel.
- Place the canapes on a baking sheet and broil until the topping is bubbly.
I saw Paula Deen make these on television today. If you can't find party rye you can cut regular size bread into fourths. These can also be served at room temperature.
