Step 1: Prepare the Vegetables: Wash and dry the mixed greens thoroughly. Halve the cherry tomatoes, slice the cucumber, and thinly slice the red onion.
Step 2: Combine Salad Ingredients: In a large bowl, gently combine the mixed greens, cherry tomatoes, cucumber, red onion, feta cheese, and Kalamata olives.
Step 3: Prepare the Dressing: In a small bowl, whisk together the extra virgin olive oil, lemon juice, and dried oregano. Season with salt and freshly ground black pepper to taste.
Step 4: Dress the Salad: Pour the dressing over the salad and toss gently to combine. Ensure that all ingredients are lightly coated.
Step 5: Serve Immediately: Serve the salad immediately. Garnish with additional feta cheese or a sprig of fresh oregano, if desired.
Optional Tips: For added protein, grilled chicken or chickpeas can be incorporated. Balsamic vinegar can substitute lemon juice. For dairy-free option, omit the feta.
