- 3 medium-sized onions, preferably red
- 1 green chili, seeded and sliced (optional)
- Juice of 1/2 lemon, or 2 teaspoons cider vinegar
- Kosher salt to taste
- Peel onions, and cut them in thin slices. Separate the shreds, and wash them in several changes of cold water, squeezing them slightly. Be careful not to squeeze the shreds too hard, or you may crush them. Put them in a bowl, add chili, and sprinkle them with lemon juice or vinegar, and salt. Toss. Serve immediately.
