Since I was making these onion sandwiches for my manly DH, I skipped the fussy steps of making miniature sandwiches, using whole slices of light wheat bread. Then I put a light layer of mayo, thin,thin,thin slices of vidalias, some fresh watercress and a tiny smear of Dijon on the other piece of bread. Wow...what a wonderful eating experience. I do heartily recommend that you have some parsley to munch after eating these sandwiches to take away any possibility of strong onion breath. It really works. Good post Angela for appetizers or for a lunch treat!
