Written in food: Tomato and Cucumber Salad

Note: I wrote this post for a blog I had a few years ago but wanted to share it with all of you, too!
This salad was inspired by a number of things, resulting in me just throwing it together one day and deciding I really liked it! I didn't measure the ingredients when I thew it together and still haven't so please bare with me on that one!
What I love about this salad is that it's so simple but such a great dish for summery meals, cookouts or large groups! It's also a great make ahead dish as it's better after sitting in the refrigerator for a few hours! I also make a big batch, resulting in left overs for days so feel free to half it for a smaller batch!
So, without further to do....
Ingredients:
2 pints small tomatoes (you can use cherry tomatoes, grape tomatoes or any other that is about that size. My favorite, though, is a mixture I get at my store of cherry, grape, yellow and a darker variety as well! It adds color and different flavors to the simple salad)
1 cucumber
vinegar
1-2 pinch of sugar
1 handful mozzarella cheese (feta would also work well)
1 onion
Directions:
* Wash the tomatoes, cucumber and onion
* Cut each tomato in halves or quarters, until the are the size you like. They should be good sized, though.
* Place all tomatoes in a large bowl
* Cut cucumber in half length wise
* Slice cucumber, creating half moon pieces (it's ok if they are not all uniform. Variety makes it rustic and pretty)
