Start by washing all your produce thoroughly. Slice the cucumbers into thin rounds and cut the bell peppers into thin strips. Thinly slice the red onion so it blends without overpowering each bite.
In a small bowl, whisk together olive oil, apple cider vinegar, honey (or maple syrup), salt, and black pepper. Taste and adjust seasoning if needed. The dressing should be slightly tangy with a hint of sweetness.
Place the sliced cucumbers, bell peppers, red onion, and parsley into a large bowl. Pour the dressing over the top. Toss gently until everything is evenly coated.
If using feta or sesame seeds, sprinkle them over the salad. Gently fold them in to avoid breaking up the vegetables too much.
For best flavor, let the salad sit in the refrigerator for about 10–15 minutes. This allows the vegetables to absorb the dressing fully and enhances the taste.
