tuna salad, sandwich

I want onion but I don't want all those onion-y sulfur compounds to permeate during storage, so it is salted to disable it and cause it to weep. 

This is a large tin.

I'm showing the liquid the onions exuded. The onions were rinsed and dried. Now they are harmless.

My bread is a bit dry and the salad sat on top of it as a separate entity unwilling to become acquainted. It was wrapped tightly and chilled. A forced marriage, as it were. The bread softened.

If you think about it, open face sandwich is an oxymoron because nothing is sandwiched between two things.
