Preheat oil on a medium pan. Add onions, salt and cook for about 5-8 minutes, stirring occasionally, until onion has started to soften. Add balsamic vinegar and cook for another couple of minutes until the onions are soft and caramelized.
Preheat the oven to 450F. Roll out the pizza dough into a round shape roughly in 13-inches in diameter. Spread the onion mixture over the pizza. Add chopped dates and fresh mozzarella cheese. Bake for 12- 13 minutes until the cheese is melted and the crust is golden brown.
Top the pizza with fresh arugula and basil leaves.
