Great fresh salad that uses early summer vegetables. Very colorful too! Cooking time is the time for soaking the onions.
- Soak the red onion wedges in salted ice water for 30 minutes and then drain well.
- Put the onion, cucumbers, and tomatoes in a large bowl and season with salt and pepper.
- Mix together the vinegar, sugar, and canola oil in a small bowl until the sugar is dissolved. Add to the vegetables and toss well. Refrigerate.
- To serve, add the chopped parsley and toss.
