Preheat the oven to 400 degrees.
Spray or dust the pizza pan with corn starch or non-stick baking spray.
Stretch the pizza dough to fit your pizza pan.
Sprinkle the cheese evenly over the surface.
Look at vegetables and herbs and think about the design you would like to make, I started by laying out the green onions for the stems first and then adding the onions.
To make the large flower onion, simply cut a 1-inch piece on the root side of the onion. Do not cut off the roots as they help hold the layers together. Make slices in the onion that will help create the look of petals, play with it a little bit until you get the shape you want, just be careful not to cut all the way through in the center where the roots hold it together.
Follow by adding the rest of the vegetables and herbs until your pizza canvas is full.
Dust with salt and pepper, spritz all over with the oil, and then bake for about 12 to 14 minutes or until the pizza is golden brown and the cheese is bubbling.
At this temperature and with the oil on top, the vegetables should nicely roast up and be tender in this amount of time.
Let the pizza cool for a few minutes before cutting. For this pizza, I used a standard large pizza rolling cutter and just cut pieces around the flower shapes to help maintain the look of the pizza.
