Preheat the oven to 400°F. Peel and cut the eggplants into thick rounds of about 1 inch thick, brush both sides with oil, sprinkle with sea salt and place on a shallow baking sheet. Place in the oven to roast until golden and cooked through, about 15 minutes. Remove, cool completely and slice each round in half. Set aside. Using a mortar and pestle, crush the fennel seeds and garlic to make a paste. Add the balsamic vinegar, honey, lemon juice, Dijon mustard, pomegranate molasses and olive oil. Whisk together to emulsify the dressing. Set aside. In a shallow serving platter lay the arugula leaves. Sprinkle the onion, tomatoes, salt and pepper on top. Toss to combine. Scatter the eggplant slices on the salad. Drizzle some dressing all over. Garnish with pine nuts and pomegranate seeds. Serve immediately, with crusty olive bread and olives on the side.
