Mediterranean Chickpea Salad

Place the onions in a bowl of cool water and let them soak while you prepare the other ingredients (this removes the harsher bite from the onions, while still giving great flavor).
Place the chickpeas, parsley, bell peppers, cucumber, and feta in a large serving bowl.
In a small mixing bowl or large measuring cup, stir together the dressing ingredients: olive oil, red wine vinegar, garlic, oregano, salt and pepper. Drain the red onions and add them to the chickpea mixture, then pour the dressing over the top. Toss to combine. If time allows, let marinate in the refrigerator for 30 minutes, or enjoy immediately.
