Preheat oven to 450 F
In meantime, prepare veggies for roasting by lightly tossing them on a roasting pan with a bit of salt, pepper and olive oil.
Roast for 25-30 or until golden and fork tender.
Prepare the onions while veggies are roasting by heating olive oil in a medium size stainless steel skillet over medium heat.
Toss in onions, olive oil and a pinch of salt and cook for about 5 minutes.
To the onions, add balsamic vinegar and sauté until vinegar has reduced down and onions have turned soft and golden brown about 10-15 more minutes.
Set cooked vegetables and caramelized onions aside and over with aluminum foil (keep the oven on and at same temperature for cooking pizza dough).
Lightly oil a pizza or roasting pan.
Roll out pizza dough and place onto pan and bake until crust is golden brown about 20-25 minutes.
Layer the onions, then vegetables then goat cheese on top of cooked dough.
Top with freshly chopped herbs.
