Cut the cucumber into half inch thick slices then cut each slice into quarters.
Add cucumbers to a medium bowl along with halved tomatoes, red onion, and fresh basil.
In a small bowl, add olive oil, balsamic vinegar or lemon juice, sugar, Italian seasoning, salt, and black pepper or red pepper flakes. Whisk thoroughly to combine.
Pour the dressing over the cucumber tomato mixture and use a spoon to toss and coat the vegetables.
Add the crumbled vegan feta cheese, if using, and give the salad one last toss. Taste and add any additional salt, black pepper, or red pepper flakes if preferred. Serve cold. Store in an airtight food-safe container in the fridge for up to 4 days.
