Begin by thoroughly washing your produce under cool water. Dice the cucumbers, tomatoes, and red onion into bite-sized pieces.

In the same large bowl, gently mix together the diced cucumbers, tomatoes, and red onion. Add finely chopped dill.

In a separate small bowl, whisk together the avocado oil or olive oil with red wine vinegar, Italian seasoning, salt, and pepper. Include sugar if desired.

Pour the dressing over the cucumber and tomato mixture. Toss gently to coat all vegetables evenly.

Crumble feta cheese over the top before serving, or chill in the refrigerator for enhanced flavors.
