Combine all the vegetables on a baking sheet. Blend all the seasonings in a small bowl. Season the vegetables with the seasoning blend.
Bake the vegetables for 30-40 minutes until fragrant and lightly-medium browned.
Pull from the oven. Let rest while you're prepping the crusts.
Place the pizza crusts on a baking sheet/sheets. Spoon marinara sauce onto the crust, spreading it all over the crust, leaving the outside 1/4-1/2 inch dry. Layer the roasted veggies on top of the pizza to your taste.
Bake in the oven for 5-10 minutes until the edges of the crusts are browned. Slice and serve.
