Prep time: 20 minutes. Cook time: 0 minutes. Total time: 20 minutes. Yield: 4 individual salad towers. Servings: 4. Salad ingredients: 2 large beefsteak or heirloom tomatoes sliced into approximately 1/2-inch rounds, 1 large English cucumber cut into thick rounds, 8 ounces firm block feta sliced into 8 thick pieces, 1/4 small red onion sliced thinly, 1/2 cup pitted Kalamata olives, optional 1/4 cup pitted green olives, 2 tablespoons chopped fresh parsley or basil, and 1/4 teaspoon freshly ground black pepper or to taste. Greek dressing ingredients: 3 tablespoons extra virgin olive oil, 1 tablespoon red wine vinegar, 1 teaspoon dried oregano, 1 small minced garlic clove, 1 teaspoon fresh lemon juice, 1/8 teaspoon salt or to taste, and 1/4 teaspoon freshly ground black pepper or to taste. Wash and thoroughly dry tomatoes and cucumber. Slice vegetables into thick even rounds. Drain and pat feta dry, then cut into 8 pieces suitable for stacking. Thinly slice onion, drain and pit olives, and chop herbs. Whisk olive oil, vinegar, oregano, garlic, lemon juice, salt, and pepper until combined. Place one tomato slice on each of 4 serving plates. Add cucumber and feta. Repeat with another tomato, cucumber, and feta layer to create 4 low, stable towers. Arrange red onion and olives around the stacks. Drizzle with dressing, sprinkle with black pepper and herbs, and serve immediately. For stable towers, choose ripe but firm tomatoes, use block feta rather than crumbled feta, pat vegetables dry, build low layers, and add dressing immediately before serving. Optional variations include roasted red peppers, toasted pine nuts, fresh basil instead of parsley, or warm pita bread served alongside. These optional additions are not included in the nutrition estimates. Prepare components ahead if desired, but assemble shortly before serving. Refrigerate leftovers promptly in airtight containers at 40°F (4°C) or colder and enjoy within 1 to 2 days for best quality. Nutrition values are approximate per serving based on 4 towers, full dressing quantity, firm feta, and optional green olives. Actual values vary by cheese and olive brands, vegetable sizes, dressing consumption, and portion size.
