Combine cucumbers, grape tomatoes, red bell pepper, beans, and feta cheese in a large mixing bowl. If using olives and red onions, add them, too.

In a small bowl or a measuring cup, whisk together red wine vinegar, olive oil, oregano, salt and pepper.
3 tablespoons red wine vinegar, ¼ cup extra virgin olive oil, 1 ½ teaspoons dried oregano, ½ teaspoon coarse black pepper, ¼ teaspoon kosher salt
Pour dressing over salad mixture and stir well to combine. Taste and add additional salt and pepper, if needed.

Notes
Cucumber note: If you are using a thicker skinned waxed cucumber, peel before using.
Feta cheese: Crumbled feta cheese doesn't work as well in this salad because it has a tendency to disintegrate and disappear. Block feta works better for a chopped salad. If you prefer, low-fat feta cheese can be substituted.
Storage: Salad will keep in the refrigerator for 3 to 4 days. Stir well before serving.
Onion tip: To decrease the sharp flavor of raw onions, soak the chopped onions in ice water for 10 minutes or so. Drain well and pat dry before using.
