Great, Easy, Unexpected Snack

I made James Beard's "onion rings" the other night for the first time in a while.  Now's the perfect moment for them - farmers' markets are filled with sweet onions just pulled from the earth, and this is the best way I know to showcase that compelling flavor.  On top of that, this is the moment when all the parsley in the garden is proud and full.

Start with a loaf of sturdy white bread.  Or traditional Pepperidge Farm sandwich white.  Using a 2 1/2 inch cookie cutter, cut circles out of the bread. Slather them with good commercial mayonnaise and sprinkle them with salt.

Slice your onions very thinly.

Chop a good amount of parsley as finely as you like.

Put a slice of onion on a circle of bread and sandwich it with another circle of bread.

Spread mayonnaise on the edge of each sandwich and roll it in chopped parsley.

These keep surprisingly well; I just ate the last of the two-day old sandwiches.  It made a perfect 10 a.m. snack.
