Easy Greek Salad

Greece is one of my favorite countries.  One of my friend's mom lived in Greece for a long time.  She made a salad similar to this.  I love the fact it does not include lettuce.
Ingredients:
1 cucumber
1 quart cherry tomatoes
1 Tbs balsamic vinegar
1 Tbs olive oil 
feta cheese
Directions:
Wash and dice cucumber, put in bowl.  Wash tomatoes and add to the cucumber. Add feta cheese (however much you like).  Top with balsamic vinegar and olive oil.  Mix well and refrigerate until ready to serve.
Options:
Add bell peppers, olives, purple onions, or any other none lettuce veggie you like.
