Start by prepping the veggies. Cut the onion in half, peel it, then cut it into thin slices. Separate the onion layers by pinching them with your fingers.
Soak the onion in a bowl with cold water for 10 minutes.
Wash, dry, and chop the tomatoes into bite-size chunks. Make sure tomatoes are at room temperature.
Wash and dry the cucumber, cut it in half lengthwise, then in half again, and dice it.You don't have to peel the cucumber, but you can do so if you want. Also, if the cucumber has a lot of seeds, you can take some out.
Add chopped tomatoes and cucumber, thinly sliced redonion drained from the water, and finely chopped parsley to a large bowl.
Season with extra virgin olive oil, vinegar, salt, and black pepper. Toss well, taste, adjust for salt, and serve.
