Something to Do with Citrus (by res ipsa loquitur)

1. Peel two or three pink grapefruit. Take off the pith, too. Slice the grapefruit crosswise and then separate the sections. Put them in a bowl and sprinkle with salt and pepper.
2. Clean a bunch of arugula.
3. (Very) Thinly slice a small red onion.
4. Get a handful of pitted, oil-cured black olives.
5. Toss all of the above together with extra-virgin olive oil and balsamic vinegar.

Don't like grapefruit? Substitute oranges or blood oranges. That's what the traditional recipe calls for. My grandfather used to make it with lemons! I like it with pink grapefruit.
