Simple salad side dish

Here's a simple side dish you can prepare in a few minutes if you have cucumber, tomato and white onion. Just chop up the ingredients and add your own favorite dressing. Mine is just a little olive oil, lemon, salt and oregano.
This is very economical and nutritious as well. Btw, did you know that cucumber is good for your hair and nails? This is because of its silicon and sulphur content. You can find other ways to use cucumber, but this side dish could be a regular part of your meals ;)
