Sun-ripened tomatoes and fresh-picked sweet corn are the very essence of summer. Here they combine in a simple, colorful salad that gets you in and out of the kitchen in no time.
Combine the dressing ingredients in a small jar and shake vigorously to combine. Set aside at room temperature while you prepare the salad.
Marinate the mozzarella in half the basil oil, with a liberal sprinkling of salt and pepper. Add the red pepper flakes and toss to combine. Let sit for 1 hour at room temperature, then add the tomatoes, corn, basil and the remaining 2 tablespoons of basil oil. Stir gently to combine. Marinate for 30 minutes at room temperature to allow flavors to meld.
Wash and dry the romaine leaves, keeping them whole. Toss in a large bowl with some of the balsamic vinaigrette.
Transfer the greens to a large platter and arrange artfully. Top with the tomato-corn mixture and grind a bit more sea salt and fresh pepper on top of the salad. Serve immediately.
