"Life is like an onion: You peel it off one layer at a time, and sometimes you weep." Carl Sandburg, Poet

The refrigerator light goes on...

Tomato and onion salads are very typical menu items in Spain. A variation of it can be found on the menu of almost every tapas bar and even fine dining restaurants. Sometimes it can be as simple as onions and tomatoes on a plate with some tuna and a couple of lemon wedges, with the chef leaving it for you to add salt and pepper.

This version is a bit more elegant, and as the recipe mentions, it is best to marinate the onions overnight. It helps take a bit of the bite out of the onions, which are then well balanced by the tomatoes and tuna.
