Place dough on a lightly floured surface and cut into 6 portions. Roll or use your hands to pull into 6 thin crusts. Transfer to prepared baking sheets, and prick crusts all over with a fork.
Combine 2 tbsp olive oil and garlic in a small dish. Brush each crust with the mixture. Sprinkle each with Parmesan and pepper.
Working with one baking sheet at a time (for maximum crispiness), bake for 10 to 12 min or until crusts are crisp and golden.
Combine 1 tbsp olive oil with lemon juice and sugar. Season with a pinch of salt and pepper.
Top pizzas with smoked salmon. Toss baby greens with parsley, chives and dressing and sprinkle over salmon. Serve immediately.
