Wash and chop cucumber, onion, tomatoes, green chili pepper into small pieces.
In a bowl, add all the chopped veggies, spices, cilantro and mix well.
Garnish with cilantro leaves and serve.
Cucumber: If using English or Persian cucumber, peel, and chop. If using regular cucumbers, slice lengthwise and scrape out seeds using a spoon. Then chop the cucumber.Onions: To reduce the strong flavor of onion, you can soak them in water for 15 minutes and then drain and use. Green chili pepper: I prefer to use birdseye, Thai green chili or Serrano green chili pepper. If you are making for kids, skip the green chillies.
