Wash and dry the vegetables and fresh herbs. Set aside.
Cut your cucumber into small chunks or slices, whichever you prefer. Add to mixing bowl.
Peel, then slice the onion as thin as you can get it. Add to mixing bowl.
Cut the tomato into chunks. Remove and discard the seeds. Add to mixing bowl.
Roughly chop the fresh basil. Measure out 3 T after chopping and add to mixing bowl.
Add all remaining ingredients (oil, vinegar, dill, salt and pepper) into the mixing bowl and gently toss to coat.
Cover the bowl and chill the salad in the fridge for at least 1 hour so flavors combine.
Taste before serving and add more salt and pepper as desired.
Notes
How you cut your cucumber and tomatoes is purely optional. Sometimes we slice them and sometimes we dice them. We have never noticed this impacting the flavor in any real way.
