In a small mixing bowl, whisk together olive oil, lemon juice, dried oregano, maple syrup or honey, minced garlic, and a pinch of salt and pepper. Set aside.

Slice cucumbers into half-moon shapes and Roma tomatoes into bite-sized chunks. Thinly slice the red onion and halve the black olives.

In a large salad bowl, combine the chopped cucumbers, tomatoes, red onions, and black olives. Toss gently.

Pour the prepared vinaigrette over the salad ingredients and toss gently to coat.

Sprinkle crumbled feta cheese over the top of the salad and garnish with fresh herbs if desired.
