Step 1: Prepare Black Lime Onions. Thinly slice the baby red onion and place it in a bowl. Add ground black lime and red wine vinegar, and massage the onion for about 20 minutes.

Step 2: Make Dressing. Whisk together olive oil, pomegranate molasses, remaining red wine vinegar, and salt until smooth.

Step 3: Prep Tomatoes. Wash and slice large tomatoes and halve cherry tomatoes. Combine in a bowl with torn basil leaves and half the pomegranate seeds.

Step 4: Assemble Salad. Arrange the large tomato slices on a platter, add the small tomato mixture in the center, top with marinated onions, and scatter the remaining pomegranate seeds.

Step 5: Serve. Season with flaked sea salt and serve immediately.
