In a large pot, boil water for the pasta and cook pasta according to package directions.
While the pasta is cooking, combine all the dressing ingredients in a mason jar or plastic container with a tight fitting lid and shake to combine.
Chop the tomatoes, cucumber, and olives and put in a large bowl with the chick peas. When the pasta is cooked, add it to the bowl with the vegetables, add the dressing and toss to combine. Top with feta cheese (optional) and serve warm or cold.
