Spray counter lightly with non-stick cooking spray. Roll combined rolls into a 10x14-inch rectangle. Place in a 9x13-inch sprayed pan. Cover with plastic wrap and let rise for 30 minutes.
Remove wrap. Press dough down with fingers to form a dimpled surface. Brush with olive oil. Top with tomato halves and fresh rosemary. Sprinkle with sea salt.
Bake at 350°F 20-30 minutes.
