Preheat oven to 420 degrees. (If you are using a different frozen or store-bought crust, follow the directions on the package for the correct temperature for pre-heating & cooking time.)
Bring a non-stick skillet to a medium heat along with oil. Crumble the veggie burger into the skillet. Saute a few minutes, until browned. Then remove from heat & set aside.
Use a spoon to cover the pizza crust in marinara. Top with browned veggie burger and shredded non-dairy cheese.
Put the pizza directly onto the oven grate & bake for 12 minutes. (The Monteli package recommends 6 to 7 minutes for baking, but I think the crust isn't crisp enough at that point.)
While the pizza is baking, chop the vegetable toppings for the pizza and make the special sauce.
When the pizza is done, remove it from the oven and cut it into 6 slices. Top it with chopped romaine, tomatoes, dill pickle slices, and minced onion. Finish with drizzles of special sauce across the pizza and serve.
