Combine together all of the dressing ingredients and whisk until emulsified. Alternatively, use a food processor or blender. Taste test the dressing and season with salt and pepper if required.
Cook pasta in salted water until al dente, then drain and rinse until cold.
In a large bowl, mix together the pasta, tomatoes, onion, olives, cucumber, pepper, and fresh dill.
Pour half of the dressing on top of the pasta salad and mix well. If you need more dressing, add a bit at a time to get the consistency just right. The remaining dressing can be served on the side or saved in the fridge for a green salad during the week.
The Greek pasta salad flavor will taste much better if chilled for at least an hour before serving. Add all of the feta and mix well right before serving. Enjoy!
