These flew off my tray last night at a dinner party! After broiling I cut the canapes on the diagonal for pretty triangles that were more bite sized. I doubled the recipe, cut back on the mayo, and increased the fresh grated Parmesan. If using jarred (not canned mushrooms, buy a top quality brand like Green Giant or Pennsylvania Dutch stems and pieces or chop sliced ones for more even distribution, and increase the onion rings. I will try fresh mushrooms next time. Toast the bread crisp and can store in a zip lock baggy. I made the mixture up the day before and added the French fried onions at the last minute so they would be crisp. I used Hellman's Real Mayonnaise as I didn't think Light would do as well. Spoon the mixture on the bread 1/2 hour ahead and broil in batches if entertaining a crowd so as to serve them hot. .

These are one of our favorite appetizers. The only problem with them is they go so fast. I haven't met anyone yet who doesn't love them. Thank you Paula for sharing this delicious recipe with us.

I decided to make these canapes for an appetizer at a last minute dinner get together. They were delicious, fast and SIMPLE to make. Everyone loved them! I substituted real mushrooms for canned, which I sautéed in some butter and cut back a bit on the mayo. Next time I will take another viewer's suggestion and subsitute the Rye party bread for a french baguette. I will definitely make this one again!
